(a)
Interpretation:
The coenzyme transfers an acyl group from one substrate to another should be determined.
Concept introduction:
Cofactors that are organic molecule are called coenzymes;
Coenzymes are derived from Vitamins which are substance needed in small amounts for normal body function that the body cannot synthesize in adequate amounts.
Thiamine pyrophosphate (TPP) is the coenzyme required by enzymes that catalyse the transfer of an acyl group.
