WebCytochrome c Oxidase (Complex IV, CcO) is the terminal electron acceptor in the electron transport chain (ETC). The ETC is located in the inner mitochondrial membrane of eukaryotic cells and the plasma membrane of prokaryotic cells [Bertini]. The ETC couples the redox transfer of electrons to the generation of a proton gradient. WebCytochrome c is primarily known for its function in the mitochondria as a key participant in the life-supporting function of ATP synthesis.
