WebMay 6, 2016 · Introduction. Cytochrome c is a heme-containing protein that normally resides in the mitochondrial inter-membrane space. It carries electrons from cytochrome c reductase (the cytochrome b-c 1 complex) to cytochrome c oxidase as part of the electron transport chain that builds an electrochemical gradient driving the synthesis of ATP. This … 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.
