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 … WebNow this is really the first step of the electron transport chain. These electrons are transported out of the NADH. Now, the last step of the electron transport chain is you have two electrons-- and you could view it as the same two electrons if you like-- two electrons plus two hydrogen protons.

WebAug 8, 2024 · Cytochromes are the proteins with characteristic absorption of visible lights due to the presence of heme containing Fe as co-factor. There are three different types of cytochrome a, b and c. Cytochrome a and b are tightly but not covalently linked with their proteins whereas cytochrome c is covalently bonded with its protein through cysteine. WebDec 16, 2024 · Complex IV contains cytochromes a and a 3 in an enzyme known as cytochrome oxidase.
