Enzymes: Classification, Kinetics and Inhibition · Zoology

The induced-fit model suggests that:

  1. Active site is rigid and fixed
  2. Substrate changes shape to fit enzyme
  3. Enzyme adjusts shape upon substrate binding
  4. Binding is entirely non-specific
Show answer and explanation

Correct answer: Enzyme adjusts shape upon substrate binding

The induced-fit model proposes that the enzyme undergoes a conformational change upon substrate binding to achieve a precise catalytic fit. This contrasts with the rigid lock-and-key model and better explains the flexibility observed in enzyme catalysis.
