"WebThe electron transport chain of photosynthesis is initiated by absorption of light by photosystem II (P 68o ). When P680 absorbs light, it is excited and its electrons are transferred to an electron acceptor molecule. Therefore, P 680 becomes a strong oxidising agent, and splits a molecule of water to release oxygen. " - The electron carrier in photosynthesis
