Which Enzyme Catalyzes The Oxidation-reduction Reaction?

Which Enzyme Catalyzes The Oxidation-reduction Reaction? An oxidase is an enzyme that catalyzes an oxidation-reduction reaction, especially one involving dioxygen (O2) as the electron acceptor. In reactions involving donation of a hydrogen atom, oxygen is reduced to water (H2O) or hydrogen peroxide (H2O2). Which enzyme are responsible for oxidation and reduction reactions? Redox enzymes are
