NEET Zoology (general) Assertion Reason Question

Type: Assertion Reason-assertion-Medium-Class 11

Assertion (A): Enzyme-catalyzed reactions proceed at rates vastly higher than uncatalyzed reactions.

Reason (R): Enzymes lower the activation energy of reactions, facilitating the transition state.

A

Both A and R are true, and R is the correct explanation of A.

B

Both A and R are true, but R is not the correct explanation of A.

C

A is true, but R is false.

D

A is false.

Correct Answer

Option A

Detailed Explanation

Enzymes catalyze reactions by lowering the activation energy, which increases the rate of the reaction as described in the catalytic cycle. This is why enzyme-catalyzed reactions are faster than their uncatalyzed counterparts.
