Detailed explanation-1: -The oxidase test is used to identify bacteria that produce cytochrome c oxidase, an enzyme of the bacterial electron transport chain. (note: All bacteria that are oxidase positive are aerobic, and can use oxygen as a terminal electron acceptor in respiration. This does NOT mean that they are strict aerobes.

Detailed explanation-2: -Cytochrome c oxidase (COX) or complex IV of the mitochondrial respiratory chain plays a fundamental role in energy production of aerobic cells. This multimeric enzyme of the inner mitochondrial membrane catalyzes the last step of respiration, the transfer of electrons from cytochrome c to molecular oxygen.

Detailed explanation-3: -The heme aa3-type cytochrome c oxidase (COX) is the terminal electron acceptor in the respiratory chain of mitochondria and many bacteria. It catalyzes the transfer of electrons from cytochrome c to molecular oxygen, a reaction that is coupled to the translocation of protons across the membrane.
