Why are two photosystems needed when water is used as an electron donor?
Homework Answers
Both the photosystem needed because one photosystem is expected to pull electrons from water and second is expected to raise the energy of these electrons enough that they can lessen NADP+ . In cyclic photophosphorylation cytochrome uses the energy of these electrons and create more ATP.
