In z scheme of electron transport
WebElectron micrograph of a 2D crystal of the LH1-Reaction center photosynthetic unit. A photosynthetic reaction center is a complex of several proteins, pigments and other co-factors that together execute the primary energy conversion reactions of photosynthesis. Molecular excitations, either originating directly from sunlight or transferred as ... WebThis chain of electron acceptors is known as an electron transport chain. When this chain reaches PSI, an electron is again excited, creating a high redox-potential. The electron transport chain of photosynthesis is often put in a diagram called the Z-scheme, because the redox diagram from P680 to P700 resembles the letter Z.

Web11 sep. 2014 · The Z-scheme includes more than 20 intermediates; in addition, there is also a Q-cycle around the cytochrome b 6 f complex, which allows for additional proton transport across the membrane, and thus more ATP, as well as cyclic electron transport involving PS I and the cytochrome b 6 f complex. WebZ Scheme. The energy changes (oxidation / reduction) that occur during photosynthesis may be represented as a Z scheme: First vertical bar: Photosystem II electrons are energised by light (electrons replaced by …
WebThe whole scheme of transfer of electrons, starting from the PS II, uphill to the acceptor, down the electron transport chain to PS I, excitation of electrons, transfer to another acceptor, and finally downhill to NADP+ reducing it to NADPH + H+ is called the Z scheme, due to its characteristic shape. The splitting of water in the presence of ... WebArrangement of electron carriers according to their redox potential. The ability of a substance to give up or take up electron depends upon its redox potential value. Substance with low redox potential will lose electrons easily and substance with high redox potential will gain electrons. Suggest Corrections. 1.
