WebMar 30, 2024 · In PS-1, the reaction centre chlorophyll a, has an absorption peak at 700 nm, hence it is called P700 whereas in PS-2, reaction centre has an absorption peak at 680 nm and it is known as P680. Hence, the correct answer is option (B). Note: Light harvesting complex helps to make photosynthesis more efficient by absorbing different wavelengths … 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 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 … See more • Oxygen evolution • P680 • Photosynthesis • Photosystem See more
WebPhotosystem 2 (PS2) is the part of the photosynthetic apparatus that uses light energy to split water releasing oxygen, protons and electrons. Here, we present a model of the … Webthat precludes measurement of the light reactions of photosynthesis by any gas exchange–based method. PAM machines calculate photosynthesis as the electron transport rate (ETR) through PSII (four electrons per O 2 produced) as mol m 2 s 1. Photosynthesis-versus-irradiance (P-vs.-E) curves fitted the waiting-in-line function (ETR …
WebP-870 + BPheo → P-870 + + BPheo – (Charge separation) . From BPheo –, the electron is transferred within micro-seconds to a tightly bound molecule of quinone (Q A), converting it into a semi-quinone radical (Q A).The electron from Q A is taken by another quinone (Q B) which is loosely bound to the membrane.Two such electron transfers convert Q B to its … WebThe light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron …
