Cytochrome respiration
WebMar 6, 2024 · Cytochrome c (Figure 5.26) is a small (12,000 Daltons), highly conserved protein, from unicellular species to animals, that is loosely associated with the inner mitochondrial membrane where it functions in electron transport. It contains a heme group which is used to carry a single electron from Complex III to Complex IV. WebCytochrome c oxidase, a membrane-bound enzyme in the respiratory chain of aerobic organisms, reduces oxygen to water. This process which takes place at the binuclear metal centre constituted by a haem a3 and a Cu ion runs via several intermediate states with life times in the micro- and millisecond range.
