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. WebCytochrome c is primarily known for its function in the mitochondria as a key participant in the life-supporting function of ATP synthesis.

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 WebJun 6, 2024 · Respiration inhibition can replicate this effect: erythromycin, an inhibitor of cytochrome synthesis (particularly cytochrome aa 3 of Complex IV), enhances sensitivity to Amphotericin B (Geraghty and Kavanagh 2003b).
