Many organisms that respire have the enzyme cytochrome c oxidase in their electron transport chain that transfers electrons to oxygen, reducing oxygen to water. This test uses a reagent (tetramethyl-p-phenylenediamine) that changes color when it becomes oxidized by cytochrome c oxidase.As oxygen is required, only organisms that are aerobes, microaerophiles, or facultative anaerobes contain cytochrome c oxidase.his test uses a reagent (tetramethyl-p-phenylenediamine) that changes color when it becomes oxidized by cytochrome c oxidase.
