cytochrome oxidase
n.
An oxidizing enzyme containing iron and a porphyrin, found in mitochondria and important in cell respiration as an agent of electron transfer from certain cytochrome molecules to oxygen molecules.
cytochrome
any of a class of hemoproteins, widely distributed in animal and plant tissue, whose main function is electron transport; distinguished according to their prosthetic group as a, b, c and d.
cytochrome b5 reductase
a flavoprotein involved in the desaturation of fatty acids in the liver.
cytochrome oxidase
an a type cytochrome which contains copper and receives electrons from another cytochrome, of the c type, and transfers them to oxygen atoms allowing the oxygen to combine with hydrogen atoms to form water. A nutritional deficiency of copper leads to a general reduction in metabolic rate because of the absence of cytochrome oxidase a.
