WebAnswer: 1. When photosystem II absorbs light, an electron excited to a higher energy level in the reaction center chlorophyll (P680) is captured by the primary electron acceptor. The … 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 …
WebQL, the acceptor observed at around - 270 mV in fluorescence titrations of higher plant PS2 pre~ratio~s, so the nature of this acceptor is as yet unknown. An iron-sulphur protein with … 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 …
WebAug 17, 2024 · Electron acceptor proteins reside within the thylakoid membrane. These proteins also become reduced as they accept electrons and oxidized as they pass electrons down this chain.
