cy·to·chrome

 (sī′tə-krōm′)
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.

The mitochondrial pathway is initiated by the release of apoptotic factors such as cytochrome c, apoptosis inducing factor (AIF) and endonuclease G from the mitochondrial intermembrane space by mitochondrial outer membrane permeabilization (MOMP), which is a complex process that involves numerous molecular players including Bcl-2 family (Brenner and Grimm, 2006; Kuwana and Newmeyer, 2003).
