Light Dependent Reaction Lab Report

The light dependent reaction is vital for photosynthesis to take place. There are six stages to this reaction. Stage one breaks down bond in water to form oxygen, while this is taking place electrons are freed along with hydrogen. This stage happens to take place in the thylakoid space. Stage two involves electrons moving to photosystem II. At this point energy from light is absorbed while in photosystem II. Therefore electrons receive more energy while being in the thylakoid membrane. Stage three takes electrons through the electron transport chain. In this stage energy is provided to transport hydrogen ions from out of the stroma into the thylakoid space. This stage also takes place in the thylakoid membrane. Stage four of the light dependent reactions involves photosystem I. While in photosystem I, light is absorbed for the movement of electrons in the thylakoid membrane. Stage five lets the electrons passing through get acquainted by NADP+. NADP+ then links with hydrogen to form NADPH in the

Step one involves two-carbon acetyl group CoA is added to the four-carbon oxaloacetate to create six-carbon citrate. Step two the citrate loses a particle of water and gains another one. The citric acid is converted to the enzyme aconitase. Step three the isocitrate loses another molecule of carbon dioxide and can be oxidized by forming the five-carbon alpha ketoglutarate. Step four the alpha ketoglutarate is changed to the four-carbon succinyl CoA. A particle of carbon dioxide is deleted and NAD+ is changed to NADH + H+ during the process. Step five CoA is removed from the succinyl particle and is changed out with a phosphate group. Step six is the oxidant of succinate while fumarate is created. FAD is reduced and creates FADH2. Step seven the water particle is added and the bonds within carbons in fumarate are changed-creating malate. The final step malate is oxidized creating
