Question

What is an Isozyme?

(a) Same structure, different function

(b) Different structure, the same function

(c) Same structure, the same function

(d) Different structure, different function

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

Query is from Enzymes in chapter Biomolecules and Catalysis of Life Sciences

Answer 1

Correct choice is (b) Different structure, the same function

The best I can explain: Isozymes are multiple forms of enzymes that have the same functions but differ in structure. For example, lactate dehydrogenase which catalyzes the conversion of pyruvate to lactate, it has five isoenzymes.
