The overall source of energy for photosynthesis is:A. energy released when water is split, and oxygen is producedB. energy from NADPHC. light energy from the sun D. energy from ATP 3. John Dela Cruz grew algae in the presence of a poison that stops the lightindependent reactions of photosynthesis. As a result, which molecules will the light-dependent reactions stop producing?A. ADP and NADP+B. ADP and NADPHC. ATP and NADP+D. ATP and NADPH
Put the steps for the formation and usage of ATP in photosynthesis in order. 1. Hydrogen ions will diffuse out of the thylakoid; the concentration of H+ ions inside the thylakoid is higher than outside. 2. ATP synthase adds a phosphate group to ADP to form ATP. 3. Potential energy is stored, so hydrogen ions can now diffuse out through protein channels in the thylakoid membranes.

When a photon of light energy reaches a reaction center chlorophyll molecule, what becomes excited?A. a molecule of water vapor C. an atom of oxygenB. a carbon dioxide molecule D. an electron 3. Two sets of reactions take place within the process of photosynthesis. Describe how does one set of reactions influence the other? A. The raw materials (reactants) of the light reactions (H2O) are reused in the Calvin cycle. B. There is no influence. Each set of reactions occurs separately, and they have nothing in common. C. Products of the light reaction (NADP+ and ADP + P) enter the Calvin cycle; products of the Calvin cycle (NADPH and ATP) are sent back to the light reactions. D. Products of the light reaction (NADPH and ATP) enter the Calvin cycle; products of the Calvin cycle (NADP+ and ADP + P) are sent back to the light reaction.

1: Photosynthesis 1. What are the main inputs (reactants) required for overall photosynthesis? Where are they used in the individual process? 2. Why do plants require light to perform photosynthesis? What is the mechanism plans have to utilize light energy in photosynthesis? 3. Which types of plants use the C4 cycle? Which types of plants utilize the Calvin Cycle? 4. Evolution led to the formation of Rubisco that is used by C3 plants to fix CO2. Why do you think that it led to an enzyme that also binds to 02 (which causes photorespiration that isn't beneficial to the plant)? 5. Explain what is meant by the statement: "C4 plants separate C3 and C4 processes in space and CAM plants separate C3 and C4 processes in time." 404 words MacBook Pro
