$Zinc$ is the co-factor for the proteolytic enzyme carboxypeptidase.

For its activity,carboxypeptidase requires

Assertion $(A)$: The structure of an enzyme consists of an apoenzyme and a coenzyme.
Reason $(R)$: $A$ coenzyme is a non-protein part that makes the enzyme active.

In co-factors,in what form are the inorganic components present?

The presence of $Zn$ is required for the activity of which enzyme?
