Assertion(A): Activity of an enzyme is `pH` dependent.
Reason(R): Change in `pH` affects the solution of the enzyme in water.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true and the reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
B
Activity of enzyme increases with increase in `Ph` and is maximum of `pH = 7.4` and then falls off. Hence, assertion is correct.
Correct explation with change in `pH` , the extent of protonation of the bases changes.
