Cyt oxidase
WebExecutive Summary. Cytochrome c Oxidase (CcO) is the terminal electron acceptor in the electron transport chain. It catalyzes the reduction of dioxygen to water, a process … WebApr 9, 2024 · Cytochrome proteins have a prosthetic group of heme. The heme molecule is similar to the heme in hemoglobin, but it carries electrons, not oxygen. As a result, the iron ion at its core is reduced and oxidized as it passes the electrons, fluctuating between different oxidation states: Fe ++ (reduced) and Fe +++ (oxidized).

WebThe oxidase test is used to determine if an organism possesses the cytochrome c oxidase enzyme. The test is used as an aid for the differentiation of Neisseria, Moraxella, Campylobacter and Pasteurella species (oxidase positive). It is also used to differentiate pseudomonads from related species.
