JEE Main levelSingle correct optionDifficulty 2 of 3el008
Assertion (A): Competitive inhibition of an enzyme can be reduced by increasing the substrate concentration. Reason (R): The competitive inhibitor and the substrate compete for the same active site. Choose the correct option.
ABoth A and R are true and R is the correct explanation of A
BBoth A and R are true but R is not the correct explanation of A
CA is true but R is false
DA is false but R is true
Answer: A
Both statements are true. Because inhibitor and substrate share the active site, a large excess of substrate wins the competition more often and displaces the inhibitor. So R explains A.
