<prompt> All of the following could include the mechanism or function of oxigenases, EXCEPT:Incorporate 2 atoms of oxygenIncorporate 1 atom of oxygenRequired for hydroxylation of steroidsRequired for carboxylation of drugs  <response>: Carboxylation is a function of carboxylase enzymes which belong to the class of Ligases. It is not a function of oxygenase enzymes. Monoxygenases incorporate one atom of oxygen and play an impoant role in hydroxylation of steroids. Dioxygenases incorporate 2 atoms of oxygen into the substrate.
