Cytochromes carry electrons
WebIt transfers electrons between Complexes III (Coenzyme Q – Cyt c reductase) and IV (Cyt c oxidase). Cytochrome c is highly water-soluble, unlike other cytochromes. It is capable of undergoing oxidation and … WebThese cytochromes do the same job as the electron carriers because as hydrogen is bounced between their cytochromes, a small amount of energy is released. The energy released by passing hydrogen atoms can rephosphorylate ADP > ATP. Electrons released from this first part of the ETC. These are used in the second part of the ETC.
