Photosystem II - Wikipedia
网页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.
Photosystem II - an overview | ScienceDirect Topics
网页Photosystem II (PSII) is the multi-enzymatic chlorophyll-protein complex in the thylakoid membrane of cyanobacteria, algae and higher plants. It catalyses the light-induced transfer of electrons from water to plastoquinone in a process that evolves oxygen (Figure 1).
