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.
