Assertion : The protein part of the enzyme is called apoenzyme and non-protein part of the enzyme is called co-factor.
Reason : Zinc is a co-factor for the proteoilytic enzyme carboxypeptidase.

Options

A. Both Assertion and Reason is true and the Reason are the correct explanation of Assertion
B. Both the Assertion and the Reason are correct and the Reason is the incorrect explanation of the Aassertion
C. Assertion is true but the Reason is false
D. Both Assertion and Reason are false

Answer

B

Explanation

Conjugate enzyme is an enzyme which is formed of two parts-a protein part called apoenzyme (e.g., flavoprotein) and a non-protein part named co-factor. The compete conjugate enzyme, consisting of an apoenzyme and a co-factor, called holoenzyme. Co-factor is small, heat stable and dialysable part of conjugate enzyme. It may be inorganic or organic in nature. Organic co-factors are of two types, coenymes and prosthetic groups. Inorganic co-factors include ions of a variety of minerals e.g., calcium, iron, copper, zinc, magnesium, manganese, potassium, nickel, molybdenum, selenium, cobalt. They usually function as activators. Zinc is required for carboxypeptidase `NAD^(+)` and `NADP^(+)` activity.
