• Haem

• Zinc

• Niacin

Answer 1

The cofactor of the enzyme carboxypeptidase is Zinc.

Explanation:

As a metalloenzyme, carboxypeptidase needs a metal ion cofactor to function. The cofactor for carboxypeptidase is usually a zinc ion. By coordinating with certain amino acid residues inside the active site of the enzyme carboxypeptidase, zinc ions play a critical role in the catalytic activity of the enzyme. promoting the hydrolysis of protein peptide bonds.
