cytochrome oxidase

n.
An oxidizing enzyme that contains iron and a porphyrin and is found in the mitochondrial membrane, where it catalyzes the transfer of electrons to oxygen as part of the electron transport chain, ultimately leading to the formation of ATP.

cytochrome oxidase

An enzyme present in most cells that oxidizes reduced cytochrome to cytochrome.

cytochrome oxidase

an enzyme acting as the last hydrogen electron carrier in the ELECTRON TRANSPORT SYSTEM, receiving an electron from CYTOCHROME and passing it on to oxygen, with the formation of water.

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.
cytochrome system
the sum of cytochromes which play a part in the body's metabolic processes. Includes the cytochrome oxidases and cytochrome reductases.
