The substrate binds to specific region of enzyme called?
Correct answer: B. Active site
- A. Key
- B. Active site
- C. Hyperactive site
- D. None of these.
Explanation
The substrate binds to a specific region of an enzyme called the active site. The active site is a three-dimensional pocket or cleft on the enzyme's surface that is precisely shaped to accommodate the substrate molecule. The interaction between the substrate and the active site is highly specific, often likened to a lock-and-key mechanism.

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
