A) Zn-Ferrocyanide inhibits the enzyme FNR and prevents reduction of NADP+ to NADPH. In the presence of Zn-Ferrocyanide, what would happen to the pH gradient, and the rates of electron transport, oxygen evolution, and ATP synthesis in the thylakoids? Explain. B) If ferredoxin cannot donate its electrons to the FNR to reduce NADP+ to NADPH, where else can it donate its electrons?

1. a. In both mitochondria and chloroplasts, ATP synthesis is coupled to electron transport. Which one of the following is likely to affect the coupling of electron transport to ATP synthesis in both of these systems? Explain. A) the absence of light B) the removal of oxygen C) leucinostatin, an ATP synthase inhibitor D)a photosystem II inhibitor 1.b. Explain why each of the other answer choices are not applicable to both of the systems.

Why is ATP synthesis in plants considered to be light-dependent? Choose the best answer for the question. Light excites P700, driving electron transfer in photosystem I. The oxidation of water at the manganese complex is light-dependent. ATP synthesis in plants is part of the Z-scheme of photosynthesis, and is driven by the transfer of electrons in photosystem II and photsystem I. The light-dependent reactions of photosynthesis set up the proton gradient that drives ATP synthsis.

Review A plant uses solar energy to make ATP and NADPH, which then drive the synthesis of carbohydrates in the leaves. At least one carbohydrate, sucrose, is translocated to nonphotosynthetic parts of the plant (stems, roots, flowers, and fruits) for use as a source of energy. Thus, ATP is used to make sucrose, and the sucrose is then used to make ATP. It would seem simpler for the plant just to make ATP and translocate the ATP itself directly to...
