An electron acceptor is a chemical entity that accepts electrons transferred to it from another compound. [1] Electron acceptors are oxidizing agents. The electron accepting power of an electron acceptor is measured by its redox potential. [2] In the simplest case, electron acceptors are reduced by one electron.
21 Ιουλ 2021 · A molecule that receives or accepts electrons from another molecule during a redox reaction. An electron acceptor is an oxidizing agent and is itself reduced during the process of redox reaction. Synonym: oxidant, oxidizing agent. See also: redox reaction, electron transport chain.
24 Δεκ 2022 · NADH is the electron donor and O 2 is the electron acceptor. Not every donor-acceptor combination is thermodynamically possible. The redox potential of the acceptor must be more positive than the redox potential of the donor.
14 Μαρ 2024 · An electron acceptor is a substance that gains electrons during a chemical reaction. It plays a vital role in electron transport chains. In biological systems, electron acceptors are crucial for energy production through processes like respiration and photosynthesis.
The reaction center of PSII (called P680) delivers its high-energy electrons, one at the time, to the primary electron acceptor, and through the electron transport chain (Pq to cytochrome complex to plastocyanine) to PSI. P680’s missing electron is replaced by extracting a low-energy electron from water; thus, water is “split” during this ...
The light excites an electron from the chlorophyll a pair, which passes to the primary electron acceptor. The excited electron must then be replaced. In (a) photosystem II, the electron comes from the splitting of water, which releases oxygen as a waste product.
