Cytochrome Oxidase

Cytochrome Oxidase (also known as complex IV) is an iron and copper containing enzyme in the electron transport system. It catalyzes the final step in the electron transport process - the transfer of electrons and protons to oxygen, to form water (Figures 15.2, 15.3, 15.10). Transfer of electrons through cytochrome oxidase can be blocked by cyanide, azide, and carbon monoxide.
