Answer #1

Option a is correct

Explanation :

Cytochrome P450 (CyP) is a host of enzymes that use iron to oxidise, often as part of the body’s strategy to dispose of potentially harmful substances making them more water soluble. These are found in plants, animals and microbes and are involved in a variety of oxidative reaction in cells. These catalyse a variety of reactions including epoxidation, A-dialkylation, o-dialkylation, .s-oxidation and hydroxylation. A typical cytochrome P450 catalysed reactions is

NADPH + H+ + O2 + RH => NADP+ + H2O + R – OH
