Wilms, A.O. This step is the last complex of the electron transport chain and comprises two cytochromes a, and a3, which are made of two heme groups and three copper ions. They have been shown to reversibly convert cytochrome oxidase from an inactive to an active coupling state by providing a suitable environment for the most active conformational state.
