Ps2 in photosynthesis
WebThe organisms undergoing noncyclic photosynthesis synthesize ATP via PS-II. Concurrently, PS-I releases electrons that the PS-I captures to reduce NADP into NADPH. It requires water hydrolysis to replenish electron loss … 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 … See more The oxygen-evolving complex is the site of water oxidation. It is a metallo-oxo cluster comprising four manganese ions (in oxidation states ranging from +3 to +4) and one divalent calcium ion. When it oxidizes water, … See more Inhibitors of PSII are used as herbicides. There are two main chemical families, the triazines derived from cyanuric chloride of which atrazine and simazine are the most commonly used and the aryl ureas which include chlortoluron and diuron (DCMU). See more Photosynthetic water splitting (or oxygen evolution) is one of the most important reactions on the planet, since it is the source of nearly all the atmosphere's oxygen. Moreover, artificial photosynthetic water-splitting may contribute to the effective use of … See more • Oxygen evolution • P680 • Photosynthesis • Photosystem • Photosystem I • Photosystem II light-harvesting protein See more

WebPhotosystem II is present on the thylakoid membranes inside chloroplasts, the site of photosynthesis in green plants. [9] The structure of Photosystem II is remarkably similar to the bacterial reaction center, and it is theorized that they share a common ancestor. The core of Photosystem II consists of two subunits referred to as D1 and D2. WebTypically, there are two photosystems categorised on the basis of the different absorption wavelengths of the chlorophyll. The two photosystems are Photosystem I and …
