Question

11. Name the molecules/energy sources/structures that best fit the following roles in photosynthesis. Use the diagrams on p.4 to refresh your memory. Choose from the following: NADPH, ATP, сог, H20, light energy, C6H1206, o.KuBP, G3P. a. the reactant that is oxidized: b. the reactant that is reduced: c. source of energy that is converted during photosynthesis: d. desired product of photosynthesis (source of potential energy & structure): e. product of Photosystem II and its E.T.C. f product of Photosystem I and its E.T.C. g. byproduct formed as a result of water splitting: h. provides energy for building glucose during the Calvin Cycle: i. directly provides H+ and e- for building glucose in the Calvin Cycle: reactant that is ultimate source of H+ and e-for Calvin Cycle: j. k. reactant that provides carbon and oxygen for building glucose in the Calvin Cycle 1. CO2 is fixed to this molecule to begin the Calvin Cycle: m. Actual product of one round of the Calvin Cycle 12. Suppose a plant has a mutation that causes the thylakoid membrane of its chloroplast to be very leaky to ions like H+. Which of the following would be the most direct effect on the photosynthesis process (choose 1)? Explain. H20 won't be split. Less O2 will be produced. Less NADPH will be produced. Less ATP will be produced. Less CO2 will be fixed. Less glucose will be produced. a. b. c. d. e. f. 13. In hot, dry conditions plants must close their stomata (pores in the leaves) to prevent water loss Which of the following would be the most direct effect stomata closing (choose from the plant. 2)? Explain. a. H20 won't be split. b. Less O2 will be produced. c. Less NADPH will be produced. d. Less ATP will be produced. e. Less CO2 will be fixed. f. Less glucose will be produced.
