B
Enzymes increase the stability of the substrate, making it less reactive.
C
All enzyme-catalyzed reactions happen at the same rate regardless of conditions.
D
Enzymes can change the products formed from a substrate during a reaction.
Correct Answer
Option A
Detailed Explanation
Enzymes indeed lower the activation energy needed for a reaction, which allows reactions to proceed at a much higher rate compared to uncatalyzed reactions, as indicated in the NCERT context regarding enzyme-catalyzed reactions.
