Assertion (A) Competitive inhibitors compete with natural substrate for their attachement on the active sites of enzymes.
Reason (R) In competitive inhibitor binds to the allosteric site of the enzyme.

A

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

B

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

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
C

Some drugs do not bind to the enzyme's active site but bind to allosteric site .
