A high concentration of H⁺ in the thylakoid compartment provides potential energy for the ____ by ____. A) breakdown of water; oxidation B) production of ATP; ATP synthases C) reduction of NADP+; an electron transfer chain D) production of sugars; the light-independent reactions E) production of O₂; photolysis

Question

Quizplus · Accepted Answer

H⁺ is a high-energy state of electron carriers in the thylakoid membrane. This energy is used to power the production of ATP by ATP synthases, which is an important step in the light-dependent reactions of photosynthesis. Option A is incorrect, as the breakdown of water occurs during the light-dependent reactions but is not directly powered by the energy of electron carriers. Option C is incorrect because the reduction of NADP+ is also a part of the light-dependent reactions, but this process is dependent on the energy provided by the electron carriers rather than providing energy itself. Option D refers to the light-independent reactions, which do not occur in the thylakoid compartment. Option E is incorrect because photolysis is the breakdown of water, which occurs during the light-dependent reactions, and is not directly dependent on the energy of electron carriers.
