1.	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.
Answer» Correct Answer - 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.
