Question

Which statements about isozymes are true?

a. Isozymes have different structures but identical functions.
b. Isozymes are encoded by the same gene but may have variations.
c. Isozymes always exhibit the same tissue distribution.
d. Isozymes perform identical biochemical reactions.

Answer 1

Isozymes are encoded by the same gene but may have variations, they do not always exhibit the same tissue distribution, and they perform similar biochemical reactions.

Step-by-step explanation:

The correct statements about isozymes are:

b. Isozymes are encoded by the same gene but may have variations.

c. Isozymes do not always exhibit the same tissue distribution.

d. Isozymes perform similar biochemical reactions, but not necessarily identical.

Isozymes are different forms of the same enzyme that perform the same function but have slight variations in structure. They are encoded by the same gene and can have different tissue distributions. While isozymes perform similar biochemical reactions, they may have slight differences in substrate specificity or reaction rates.
