What is the function of Cytochromes in Cellular Respiration?

WebMany respiratory cytochromes contain two molecules of b-type heme in their transmembrane domains.A long-standing goal in cytochrome design is therefore the creation of a minimal protein architecture that can house two b-type hemes at an appropriate distance and orientation for electron transport within, and across, a cellular lipid … WebCytochrome P4502E1 (CYP2E1) was originally designated the microsomal ethanol-oxidizing system. It associates with NADPH-cytochrome P450 reductase in the microsomal membrane and reduces molecular oxygen to water as ethanol is oxidized to acetaldehyde. CYP2E1 has a high K m for ethanol; thus it has a greater role when blood ethanol levels … highgrove nursing home brighton
