Cytochrome function
WebThe Cytochrome c oxidases are the last enzyme in the respiratory electron transport chain of the mitochondria. The main function is to convert molecular oxygen to water and aid in establishing mitochondrial membrane potential. Cytochrome c oxidase is located in the inner membrane and separates the mitochondrial matrix from the intermembrane space. WebApr 1, 2004 · Cytochrome c shuttles these electrons in the narrow space between the two mitochondrial membranes. It diffuses from protein to protein, picking up electrons from one huge membrane-bound complex and placing them at their final destination on another. But cytochrome c has a darker side as well.

WebWhat is the function of cytochrome P450? Background: The cytochrome P450 (CYP) enzymes are membrane-bound hemoproteins that play a pivotal role in the detoxification of xenobiotics, cellular metabolism and homeostasis. Induction or inhibition of CYP enzymes is a major mechanism that underlies drug-drug interactions. WebCytochrome c is known to be involved in electron transfer from ubiquinol–cytochrome c-oxidoreductase (complex III) to cytochrome c-oxidase (complex IV) in the mitochondrial respiratory chain.Type c heme (hematoporphyrin) is the prosthetic group in cytochrome c that ensures its electron transfer function [].X-ray diffraction analysis and NMR …
WebThe role cytochrome c oxidase plays is to remove electrons from the chain by transferring them to O 2 with H + to produce water. In aerobic bacterial species that do not have cytochrome c oxidase, this process still occurs, but using an enzyme that has a different structure and different name than cytochrome c oxidase.
