During photophosphorylation, the energy to produce ATP is provided by A) heat. B) NADPH. C) ground-state chlorophyll. D) the pH gradient generated during electron transport. E) NADP⁺ reductase.

Question

Quizplus · Accepted Answer

The energy to produce ATP during photophosphorylation is provided by the pH gradient generated during electron transport. As electrons are transferred through the electron transport chain, protons are pumped from the stroma into the thylakoid lumen, creating a concentration gradient. This gradient is then used by ATP synthase to produce ATP through chemiosmosis.
