WebCorrect option is A) Cytochromes are haemoproteins containing haeme groups and are primarily responsible for the generation of ATP via electron transport. They are found either as monomeric proteins (e.g., cytochrome c) or as subunits of bigger enzymatic complexes that catalyze redox reactions. WebJan 29, 2002 · Cytochrome c is often released from mitochondria during the early stages of apoptosis, although the precise mechanisms regulating this event remain unclear. In this study, with isolated liver mitochondria, we demonstrate that cytochrome c release requires a two-step process. Because cytochrome c is present as loosely and tightly bound …

However, when a cell … Cytochromes P450 (CYPs) are a superfamily of enzymes containing heme as a cofactor that function as monooxygenases. In mammals, these proteins oxidize steroids, fatty acids, and xenobiotics, and are important for the clearance of various compounds, as well as for hormone synthesis and breakdown. In 1963, Estabrook, Cooper, and Rosenthal described the role of CYP as a catalyst in steroid hormone synthesis and drug metabolism. In plants, these proteins are important for the …

WebCytochrome oxidase. Cytochrome oxidase (cytochrome c : O 2 oxidoreductase, EC 1.9.3.1) is the enzyme responsible for the oxidation of cytochrome c by oxygen. Two cytochromes have been assigned a role in cytochrome oxidase, namely cytochrome a and, as first shown by Keilin and Hartree (1939), cytochrome a3 (Chance, 1952).

The cellular location of cytochromes depends on their function. They can be found as globular proteins and membrane proteins .
