Quizplus · Accepted Answer

The lock-and-key analogy for enzymes applies to the specificity of enzymes binding to their substrate. Just as a key fits specifically into a lock, a substrate molecule fits specifically into the active site of an enzyme. This specificity is crucial for the catalytic activity of enzymes.
