WebCellular respiration sustains aerobic life and involves the oxidation of nutrients, with the final production of carbon dioxide and water. During this process, oxidation energy is captured in the form of adenosine triphosphate (ATP) molecules. Most of the oxygen is reduced to water by cytochrome c oxidase in a four-electron process. However, a small …

WebEach cytochrome c only carries one electron, thus four cytochrome c molecules must be reduced to complete the reaction. In the process of dioxygen reduction, CcO also pumps four protons across the inner membrane. The net reaction is as follows: 4Cyt cred + 4H+ + O2 + 4H+matrix → 4Cyt cox + 2H2O + 4H+intramembrane space 1.2 Structure 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. WebMar 9, 2024 · To carry out aerobic respiration, a cell requires oxygen as the final electron acceptor. A cell also needs a complete Krebs cycle, an appropriate cytochrome oxidase, and oxygen detoxification enzymes to prevent the harmful effects of oxygen radicals produced during aerobic respiration. how do you spell wetter
