Quizplus · Accepted Answer

Photolysis is not a function of the cyclic pathway but instead is a function of the noncyclic pathway, which involves both photosystem II and I. Photolysis is the process by which water molecules are split (hence "lysis") by light energy in photosystem II, producing oxygen gas and protons. It occurs in the light-dependent reactions and is the source of oxygen in photosynthesis. It indirectly replaces electrons lost by p680 by providing the protons necessary to create a proton gradient to power ATP synthesis.
