CentralNotice From Wikipedia, the free encyclopedia Jump to navigation Jump to search Process in which a series of electron carriers operate together to transfer electrons from donors to any of several different terminal electron acceptors to generate a transmembrane electrochemical gradient. The electron transport chain in the mitochondrion is the site of oxidative phosphorylation in eukaryotes . The NADH and succinate generated in the citric acid cycle are oxidized, which provides energy to power ATP synthase . Photosynthetic electron transport chain of the thylakoid membrane . The electron transport chain ( ETC; respiratory chain [1] ) is a series of protein complexes that transfer electrons from electron donors to electron acceptors via redox reactions (both reduction and oxidation occurring simultaneously ) and couples this electron transfer with the transfer...
