- DRAW a curved arrow mechanism for photosynthesis with the following steps. Step 1: Absorption of sunlight and excitation of chlorophyll molecules Step 2: Transfer of energy to reaction center chlorophylls, which lose an electron and become oxidized. Step 3: Electron transfer from oxidized chlorophylls to an electron acceptor, such as a quinone molecule Step 4: Electron transfer from the quinone molecule to a chain of electron carriers, such as cytochromes, which generate a proton gradient across the thylakoid membrane Step 5: ATP synthesis by ATP synthase using the energy of the proton gradient. Step 6: Transfer of electrons from the electron carriers to the enzyme rubisco, which catalyzes the carboxylation of ribulose bisphosphate (RuBP) with CO2, forming an unstable 6-carbon intermediate. Step 7: Cleavage of the 6-carbon intermediate into two 3-carbon molecules, which are phosphorylated by ATP and reduced by NADPH to form glyceraldehyde-3-phosphate (G3P) Step 8: Conversion of G3P to…Describe the light reaction of photosynthesis. Be sure to include its location.Draw a diagram of the dark phase of photosynthesis. You must represent this phase in the form of a cycle indicating the parts of carboxylation, reduction, generation of hexoses and regeneration. Ribulose, CO2, rubisco, phosphoglycerate (PGA), bisphosphoglycerate, phosphoglyceraldehyde (PGAL), ATP, ADP, NADPH, NADP, kinase, fructose, and glucose should appear.

All of 1,2,3 and 4 are correctExplain in detail of the stages of photosynthesis without explaining all the reactions of each pathways, but state the key steps of each pathway. Mention the location where each pathway happens in the plant and lastly make a table of the products formed at the end of the stage (ATPs, NADPHs, and water). Discuss about the oxidation-reduction of various molecules that are a part of these pathways.
- Select ALL of the following that are involved in photosynthesis. Calvin Cycle Photosystem III Photosystem I Photosystem II1) What type of organisms can carry out photosynthesis? 2) Why is photosynthesis important? 3) Draw a chloroplast and label the stroma, thylakoid, and granum, and lumen. 4) What is chromatography? 5) Write the equation for photosynthesis: Styles 6) Where do the light and dark reactions or Calvin Cycle occur in the plant? Accessibility: Good to go Q Search L 29 9 dWhat are the stages of the Calvin-Benson cycle? Select all that apply. The resulting unstable six-carbon molecule splits into two three-carbon molecules of PGA. ATP and NADPH are used to convert PGA molecules to PGAL. Most of the PGAL is used to regenerate RuBP, but some is exported to the cytoplasm to produce carbohydrates. Rubisco attaches CO2 to a five-carbon organic compound called RuBP. Rubisco is used to convert PGA molecules to PGAL.
