Biochem/physiol Actions

Cytochrome c oxidase is the principal terminal oxidase of high oxygen affinity in the aerobic metabolism of all animals, plants, yeasts and some bacteria. It is present in the mitochondria of the more highly developed cells and in the cytoplasmic membrane of bacteria. Cytochrome c oxidase catalyses the electron transfer from cytochrome c to O₂. This electron-transfer process produces a proton gradient across the membrane, which in turn drives the production of ATP. This enzyme is unique in providing energy for the cell bycoupling the electron transport through the cytochrome chain with the process of oxidative phosphorylation.
