The cafactor of nitrate reductase isA. CuB. ZnC. CaD. Mo

1.	The cafactor of nitrate reductase isA. CuB. ZnC. CaD. Mo
Answer» Correct Answer - D Reduction of nitrate to nitrite is carried out by the agency of an inducible enzyme called nitrate reductase. The enzyme is a molybdoflavoprotein (with a cofactor Mo). It requires a reduced coenzyme (NADH or NADPH) for its activity the reduced coenzyme is brought in contact with nitrate by FAD or FMN. `NO_(3)^(-)+NAD(P)H+H^(+)underset(FAD//FMN)overset("Nitrate reductase")toNO_(2)^(-)+H_(2)O+NADP^(+)`
