  • Photosynthesis, Team R For our video, we chose to show the process of photosynthesis through a few thorough scientific steps in a humorous way that will allow viewers to intake information with a little comic relief. Photosynthesis is a metabolic process by which an organism in takes light energy then converts it into chemical energy that can be used in to propel energy throughout an organism. Photosynthesis is a very intense process that we have summed up recognizing that our video does not amount to the extravagant and intricate step-by-step progression of the conversion of energy that occurs mechanically. In our video, each person had a short dialogue summing up one of photosynthesis steps. In the light reaction of photosynthesis, as a molecule of chlorophyll absorbs light in the orange-red and blue violent ranges of wavelengths, one proton then loses one electron (shown as the balloon). This allows the flow of electrons down the electron transport chain. Because of the lost electron, the chlorophyll takes one from the water molecule. During this process water frees oxygen diffuses out of the cell into the air, which is called photolysis. A proton gradient is then produced. ATP synthase and the breakdown of phophorylates and inorganic phosphate into ATP, breaks down this gradient in the thykaloid membrane. The whole process leads to not only glucose but also the most fundamental element a human needs to survive, the release of oxygen. In short, our video was taped in order to give viewers a ...
  • Photosynthesis and the light-dependent reaction Photosynthesis is the only process that converts light energy into chemical energy. The light dependent reaction, which is the concentration of this video, occurs in the chloroplasts of a leaf. This reaction is initiated by a photon of light, and goes through several steps such as: photolysis of water, excitement of the cytochrome, and pumping of protons from the stroma into the thylakoid space. In result of the previous steps, protons start to accumulate in the thylakoid space making its pH acidic. In fact when the ATP synthase senses the pH of 5, a small tube opens in the complex protein structure, and passive transport of protons from the thylakoid membrane out to the stroma occurs. These protons move through the ATP synthase at a high speed carrying with them an enormous amount of energy, it is this energy that is used to create molecules of ATP through the process of photophosphorylation.

The incidence of roentgenologically visible pineal gland calcification is approximately twice as common in American whites as in blacks, a difference that is very striking after age 40. Comparison of this finding with reports in the literature shows that the incidence of pineal gland calcification is slightly higher in American blacks than in indigenous Africans, probably due to racial mixture among the American blacks we studied. It appears that the low incidence of calcified pineal shadow already observed in the African has a constitutional basis. reference: www ...

  • Oxygen Cycle Check us out at The Oxygen cycle is the biogeochemical cycle that describes the movement of oxygen within and between its three main reservoirs: the atmosphere (air), the total content of biological matter within the biosphere (the global sum of all ecosystems), and the lithosphere (Earth's crust). Failures in the oxygen cycle within the hydrosphere (the combined mass of water found on, under, and over the surface of a planet) can result in the development of hypoxic zones. The main driving factor of the oxygen cycle is photosynthesis, which is responsible for the modern Earth's atmosphere and life. By far the largest reservoir of Earth's oxygen is within the silicate and oxide minerals of the crust and mantle (99.5%). Only a small portion has been released as free oxygen to the biosphere (0.01%) and atmosphere (0.36%). The main source of atmospheric oxygen is photosynthesis, which produces sugars and oxygen from carbon dioxide and water: 6CO2 + 6H2O + energy → C6H12O6 + 6O2 Photosynthesizing organisms include the plant life of the land areas as well as the phytoplankton of the oceans. The tiny marine cyanobacterium Prochlorococcus was discovered in 1986 and accounts for more than half of the photosynthesis of the open ocean. An additional source of atmospheric oxygen comes from photolysis, whereby high energy ultraviolet radiation breaks down atmospheric water and nitrite into component atoms. The free H and N atoms escape into space leaving O2 in the ...
  • The Birth of the WIK-WIP OK, now I want to give to Mankind a great Present! Now I give you all my Input without any return! The majority of you are using still a damned Spark Plug. Why? Every video show the same problem. I see always a mist between the electrodes or water film on them. And all the spark plugs are arranged horizontal on tables or turned with the electrodes to the sky. Some of you had the idea to conduct some vapour to the Gap. Forget these please! It is the wrong way! I recognized immediately that this is your main problem. Now listen to me! Forget all spark plugs and create a totally new one! If you want to hold water on or between the electrodes you should use a sponge! I solved with my WIK-WIP a second problem that you all have with your spark plugs still our days. My WIK-WIP can conduct through the plus electrode water and will charge the tungsten sponge after each ionisation immediately with water. As you can see in the video, I have no Tungsten-Sponge. The problem is nobody can buy the tungsten filter. They are still not produced! And therefore nobody have a chance to make experiments with them. I think we can convince some special companies who work with tungsten to start a mass production for us. A sponge of tungsten will be better. But there can be also a problem with them too. Tungsten will react with hot oxygen to tungsten three oxide and will not live too long as we want. I don't know! I hope the water from the inside will cool the heating area.

  • Cooking with Laurtoria Photosynthesis is a very complex process; therefore, our group has decided to explain photosynthesis by decorating a cake, which represents the chloroplast, and using candy on the cake, which represents the parts within the chloroplast. To show the entire process from start to finish we have put together a food show that outlines each step of photosynthesis. The twizzler that separates the two halves of the cake represent the Thylakoid Membrane. The two halves represent the Thylakoid space and the Stroma. The three circular gummies located on the twizzler represent the accessory protein, the cytochrome, and the site where ATP synthase takes place. On top of the accessory protein we have placed three green dots using icing that signifies the chlorophyll. Two marshmallows and a gummies make up the water molecule that will undergo photolysis, and the tiny raisins placed on the water molecule and the accessory proteins epitomize the electrons that are released during photosynthesis. We begin by explain photosynthesis by turning on a lamp that acts as the sun hitting the chlorophyll and absorbing the suns energy. We then take away one of the raisins from the accessory protein to display how an electron is released out of the orbit due to the photon absorbing the light. The oxidized chlorophyll molecule replaces the lost electron with an electron, or raisin, from the water molecule. This results in the water molecule to break apart which is called photolysis. We show how the ...

  • Photosynthesis_0003.wmv Our video is an overview of the process of photosynthesis. We examine the ?who, what, where, how, and why? of photosynthesis. The video runs through the steps involved in the photosynthetic process, trying to explain the entire complicated process in visual and understandable terms. We broke it down into three main sections of the process- the accessory protein, the cytochrome, and the ATP synthase. Each step of the process is textually described and visually depicted. We made a point of defining key terms throughout the video, such as photolysis, the chemiosmotic gradient, adenosine triphosphate, endergonic reactions, phosphorylation, etcetera. After describing the process of photosynthesis, we end our video with the importance of photosynthesis, which is that it produces oxygen and cellular energy. music: Step up 2 Final Showcase Mix

  • EOS - Sub-Nanosecond Transient Absorption Spectrometer EOS is a broadband pump-probe sub-nanosecond transient absorption spectrometer with an extended time window. Its patent pending design utilizes a photonic fiber for probe light generation. To the researchers using femtosecond transient absorption for studying ultrafast kinetics of photoinduced processes it is often desirable to extend the time window of investigation beyond several nanoseconds. The most widely used method in this case is Nanosecond Flash Photolysis. This technique requires a dedicated Q-switched laser with accompanying wavelength conversion equipment, laser table, additional flash photolysis spectrometer, etc. Outside of the need to set up an additional laser spectrometer, the main disadvantage of this method is its relatively low time resolution a typical IRF in the nanosecond flash photolysis experiment is 7-10 ns. Therefore even when combined the above two methods often do not allow for reliable measurements of sub-10 ns lifetimes. The EOS with its ~500 ps time resolution and the electronically controlled pump-probe delay presents a perfect solution and in combination with the HELIOS provides continuous temporal coverage from femto- to milliseconds and beyond.
  • Natural Science photosynthesis video.wmv There are three ways in which cells get the energy to phosphorylate APD. One of these methods is photosynthesis, which occurs in the Chloroplast. In order for photosynthesis to begin, photons of light of the appropriate wavelength must be absorbed by the chlorophyll molecule, located in the Thylakoid Membrane, a phospholipid membrane within the chloroplast. Then, one of the electrons surrounding the chlorophyll molecule is lost. The chlorophyll molecule will require a replacement electron, so the accessory protein grabs one from a nearby water molecule, which then falls apart. This part of the process is known as photolysis, and oxygen is produced. Next, protons begin to accumulate in the thylakoid space. The electron which had been lost previously is passed onto the cytochrome molecule, which gets excited and starts to pump protons across the thylakoid membrane. This leads to the formation of the chemiosmotic gradient, because the inner side of the membrane becomes more acidic than the outside. Then ATP Synthase, also located in the thylakoid membrane, opens up and the accumulated protons fly out. The energy of the escaping protons is captured by ATP synthase, and is used to phosphorylate ADP into ATP. In this manner, light energy from the sun is converted to chemical energy.
  • photosynthesis .mov The photosynthesis process is a unique process which allows plants to produce energy. It is the only process on earth that converts light energy into chemical energy. The process all begins when a photon of light, of the appropriate wavelength, hits the chlorophyll molecule. The chlorophyll molecule absorbs the energy from the photon, but loses one electron in the process. The oxidized chlorophyll must now replace the lost electron. The accessory protein, located in the thylakoid membrane grabs an electron from a nearby water molecule. As a result, the water molecule becomes unstable and falls apart. During this stage, photolysis takes place and oxygen is given off. The oxygen proceeds to leave the thylakoid space and the electron is passed to the cytochrome. The cytochrome then pumps protons from the stroma across the thylakoid memberane. There is now a constant supply of protons from photolysis and the excited cytochromes. In addition, there is also a constant supply of water molecules due to the aqueous environment in the thylakoid space. Due to the buildup of protons in the thylakoid space, a chemiosmotic gradient is created. When the thylakoid space reaches a pH of 5, the protein complex ATP synthase opens up a little tube. Protons from the thylakoid space rush through the tube and carry with them enormous energy, similar to how dams provide energy using water. The energy carried by the protons phosphorylates ADP into ATP. By Emily Schadt, Luke Mulkern, Jonah ...

  • Photolysis Where does the air we breathe come from? It is actually a very complicated process that produces the oxygen we so often take for granted. It begins with a plant, specifically the leaves of a plant. Photosynthesis takes place within the leaves of the plant. Photosynthesis takes place inside an organelle called the chloroplast. Within the chloroplast there are thylakoids. Each thylakoid completes the process of photosynthesis across its membrane. It is the unique process that the thylakoid membrane's integral proteins perform that produces oxygen. There are two different kinds of photosynthesis: light-dependent and light-independent. The light-dependent reaction produces energy. The light-independent reaction produces glucose. During the light dependent reaction something called photolysis or photodissociation occurs. This means that a water molecule has fallen apart. This sends free oxygen into the air for all breathing creatures to enjoy.
  • Photosynthesis In this video, we convey the importance of photosynthesis as a metabolic pathway. Without the igniting fuel of the suns rays, life on Earth as we know it would cease to exist. Through the light-dependent and light-independent reactions of photosynthesis, the metabolic cycle is fueled; this cycle consists of photosynthesis, glycolysis and aerobic resipiration. Through photolysis in the light-dependent reaction, the oxygen we breathe is released and the ATP that is needed to further fuel the cycle is produced. Without this oxygen, or without photosynthesis, life would return to an anaerobic environment like the primordial soup.
  • Dance Your PhD: Tropospheric N2O isotopic composition Nitrous oxide (N2O) is a significant greenhouse gas and in the stratosphere contributes to the catalytic destruction of ozone. Concentrations have been increasing since the beginning of the industrial era, attributed to human excess input of nitrogen through intensive agriculture and runoff into oceans, yet understanding of the processes, sources, and sinks of this gas lags far behind that of other important trace gases such as carbon dioxide, methane, and CFCs. The isotopes of N2O (most importantly 15N14N18O, 14N15N18O, 14N14N18O, 14N14N16O) can help elucidate the remaining uncertainties because the different source/sink processes preferentially use heavier or lighter isotopes and thus leave their mark on the atmospheric isotope composition. This PhD research is initiating instrumentation and measurement of N2O isotopes in the troposphere to utilize this extra information about N2O cycling. The dance follows the N2O cycle and demonstrates the fractionation of isotopes which will leave a signature in the tropospheric measurements. All three dancers are N2O molecules, starting on the ground in the soil which is the main source of N2O. N2O is emitted from the soil lightest isotope to heaviest, and the dancers "move on up" in this order. In the troposphere N2O acts as a greenhouse gas through the absorption of radiation in 3 vibrational modes. With one hand as a nitrogen atom, torso as central nitrogen, and the other hand as an oxygen atom, the dancers exhibit the three ...
  • How do cells get the energy to phosphorylate ADP into ATP? Photosynthesis is the only process on earth that converts light energy into chemical energy. Carbon dioxide, water, and sunlight are the raw materials involved in the process and glucose and oxygen are the end products. Photosynthesis occurs in two stages. The first phase is the light-dependent reactions and captures the energy of light and makes high-energy molecules. Sunlight hits the chlorophyll molecule and has to be a certain wavelength (red orange or blue violet). In the second phase, the light-independent reaction uses the high-energy molecules to capture carbon dioxide. In the light reactions one molecule of the pigment chlorophyll absorbs one photon and loses one electron. The chlorophyll molecule regains the lost electron by taking one from a water molecule through a process called photolysis. Oxygen gas is released into the atmosphere as a bi-product. Photosynthesis is affected by the amount of carbon-dioxide and light in the atmosphere.

  • A single source femtosecond-millisecond broadband spectrometer A single source femtosecond-millisecond broadband spectrometer EC Carroll, MP Hill, D. Madsen, KR Malley, and DS Larsena Department of Chemistry, University of California, Davis, One Shields Avenue, Davis, California 95616, USA Time-resolved measurement of population dynamics extending over femtosecond to millisecond time scales typically requires a combination of transient absorption techniques involving different laser systems and detection schemes. The spectrometer design presented here facilitates transient absorption measurements over 12 decades with a single ultrafast laser system by picking pump and probe pulses independently from the laser oscillator pulse train. Unamplified pulses seed a photonic crystal fiber to a supercontinuum probe source for spectrally resolved measurements. The utility of the system is demonstrated by measuring triplet state dynamics following photoexcitation of vitamin B6 in aqueous solution. Time-resolved transient absorption TA, or optical pump-probe, spectroscopy has become an indispensable technique for characterizing photoinduced population dynamics in biological, chemical, and solid-state chromophores. Dynamics in such samples often occur over multiple time scales ranging from femtoseconds eg photoisomerization to milliseconds eg protein conformational changes. In a TA experiment, a pulsed light source excites a subpopulation of the sample into an electronic excited state and its relaxation dynamics is subsequently probed by ...

  • Parshat Beshalach 5771 ● Mathematical and scientific parallels to the splitting of the waters -- Closed captioned -- The splitting of the waters at the Red Sea serves as a model for similar mathematical and scientific "splits." Most notable is photolysis, a part of the photosynthesis reactions whereby a photon of light splits water, H2O, into hydrogen and oxygen. Treating water as 10 protons (2 in hydrogen and 8 in oxygen), splitting water can be likened to dividing 10 into 2 and 8. Similarly the Ten Commandments divide into 2 and 8. The other divisions of 10 (1-9, 3-7, 4-6, and 5-5) and their special place in Judaism are also discussed.

The photoinduced transient species are investigated by passing the output of a white light emitting diode (LED) through the sample. Using an LED as a probe light source results in superior stability and low noise. The probe wavelength range of Kronos is 425-700 nm. After traveling through the sample, the probe light passes through an interference filter. After that a 10 nm wide section of the spectrum is delivered to the detector photodiode. The detector voltage output is digitized and transferred to a PC for generation of a kinetic trace and for further manipulations.
