n.
Any of a class of usually colored proteins that contain a heme group, are electron carriers, and catalyze oxidation-reduction reactions during cellular respiration.

cytochrome

(ˈsaɪtəʊˌkrəʊm)
n
(Elements & Compounds) any of a group of naturally occurring compounds, consisting of iron, a protein, and a porphyrin, that are important in cell oxidation-reduction reactions

cy•to•chrome

(ˈsaɪ təˌkroʊm)

n.
any of a series of compound molecules, consisting of a protein and a porphyrin ring, that participate in cell respiration by the stepwise transfer of electrons, each cytochrome alternately accepting and releasing an electron at a lower energy level.

cy·to·chrome

(sī′tə-krōm′)
Any of a class of proteins that are important in cell metabolism and respiration. By comparing different kinds of cytochromes, scientists can trace the evolutionary relationships of the organisms in which they occur.
