The catalytic activity of enzyme is restricted to a small portion called _.
Correct answer: A. Active site
- A. Active site
- B. Passive site
- C. Allosteric site
- D. Regulatory site
Explanation
Enzymes have two sites, active and allosteric. The active site is the one where a substrate is attached and converted into a product. Hence, option A is the correct option.

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.
