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 … 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.

WebJun 8, 2024 · The fourth complex is composed of cytochrome proteins c, a, and a 3. This complex contains two heme groups (one in each of the cytochromes a and a 3) and … The heme group is a highly conjugated ring system (which allows its electrons to be very mobile) surrounding an iron ion. The iron in cytochromes usually exists in a ferrous (Fe ) and a ferric (Fe ) state with a ferroxo (Fe ) state found in catalytic intermediates. Cytochromes are, thus, capable of performing electron transfer reactions and catalysis by reduction or oxidation of their heme iron. The cellular location of cytochromes depends on their function. They can be found as globular proteins
