Some cytochromes are mobile electron carriers that can shuttle electrons between respiratory complexes. These electron carriers are common in facultative anaerobic bacteria, and may transport electrons between the cytochrome bc 1 complex and cytochrome c oxidases and between the quinone pool and various reductases.
WebJun 11, 2024 · Cytochrome. Cytochromes are electron-transporting protein pigments concerned with cell respiration that contain an iron-containing molecule called heme, allied to that of hemoglobin. When the iron of heme accepts an electron, it changes from the oxidized ferric (Fe III) state to the reduced ferrous (Fe II) state.The oxidation of … WebDec 9, 2024 · Complex 1 to 4 are carriers of electrons while complex 5 is responsible for ATP synthesis. Besides these enzyme complexes, there are certain mobile electron carriers in ETC. This includes NADH, Coenzyme Q, Cytochrome C, and oxygen.
