Primary acceptor of ps2

Photosystem II (or water-plastoquinone oxidoreductase) is the first protein complex in the light-dependent reactions of oxygenic photosynthesis. It is located in the thylakoid membrane of plants, algae, and cyanobacteria. Within the photosystem, enzymes capture photons of light to energize electrons that are then transferred through a variety of coenzymes and cofactors to reduce plastoquinone to … WebSolution. The correct option is B. Pheophytin. Pheophytin is the primary electron acceptor for PS II. It picks up the electron given out by P 680 and passes it to the next electron acceptor plastoquinone, which further passes it to …
