<prompt> All of the following results in detoxification of drugs except-NADPH cytochrome P450 reductaseCytochrome P450Cytochome oxidaseMonooxygenase  <response>: Ans. is c i.e., Cytochrome oxidase o Drugs can be metabolized by cytochrome P450 dependent oxidations and cytochrome P450 independent oxidations i.e., by monoxygenases. o NADPH cytochrome P450 reductase is same as flavin monooxygenase. o Cytochrome oxidase is involved in respiratory chain and not in drug metabolism.
