Which of the following is a co-factor for the proteolytic enzyme carboxypeptidase?

Step-by-step solution

Enzymes are proteinaceous in nature. Some enzymes also contain non-protein part known as co-factors. These factors are attached to the enzyme to enhanced their catalytic activity. The protein part of the enzyme is known as apoenzyme. Hence, apoenzyme (protein part) + Co-factors (non-protein part) = holoenzyme (whole enzyme).As the co-factors are bound to enzymes, the removal of these factors affects the overall activity of enzymes too. These co-factors can be organic or inorganic. Organic cofactors if tightly bound
