The theory of enzyme mechanism that suggests a rigid,inflexible molecule is the ________ model.

Question

Quizplus · Accepted Answer

The lock-and-key model suggests that the enzyme has a rigid and inflexible active site that perfectly matches the shape of its substrate, like a key fitting into a lock. This model proposes that the enzyme and substrate do not undergo any conformational changes upon interacting. Therefore, the lock-and-key model is the only option out of the given choices that aligns with the statement in the question.
