Question

Quizplus · Accepted Answer

The electrons lost from the reaction center of photosystem I are replaced by electrons from photosystem II. Photosystem II receives electrons from water during the light-dependent reactions of photosynthesis. As electrons move through the electron transport chain between photosystem II and photosystem I, they release energy which is used to generate ATP.
