Question

What is the nature of an enzyme?

(a) Vitamin

(b) Lipid

(c) Carbohydrate

(d) Protein

This question was posed to me by my school principal while I was bunking the class.

I want to ask this question from Enzymes topic in section Biomolecules and Catalysis of Life Sciences

Answer 1

The correct choice is (d) Protein

To explain: All enzymes are protein except Catalytic RNA molecule. The native protein conformation of an enzyme defines its catalytic activity. Once the enzyme is denatured, its catalytic activity is also lost.
