Cyctochrome oxidase
WebCytochrome c Oxidase (CcO) is the terminal electron acceptor in the electron transport chain. It catalyzes the reduction of dioxygen to water, a process involving the addition of four electrons and four protons. This reduction is also coupled to the pumping of four protons across the mitochondrial inner membrane, which assists in the generation ... Webcytochrome oxidase n. An oxidizing enzyme that contains iron and a porphyrin and is found in the mitochondrial membrane, where it catalyzes the transfer of electrons to oxygen as part of the electron transport chain, ultimately leading to the formation of ATP.
