cytochrome oxidase
cytochrome oxidase An enzyme complex comprising the terminal two cytochromes (cytochromes a and a3) of the respiratory chain in the mitochondria (see electron transport chain). It is responsible for the reduction of oxygen, receiving two electrons from cytochrome c (which precedes it in the chain) and combining them with two hydrogen ions and an oxygen atom to form water.
