The reaction takes place in a small part of the enzyme called:
Correct answer: D. Active site
- A. Allosteric site
- B. Globular site
- C. Reactive site
- D. Active site
Explanation
The reaction takes place in the active site of an enzyme. The active site is a specific region within the enzyme where the substrate binds and the chemical reaction occurs, leading to the formation of the product. It provides a unique microenvironment that facilitates the reaction by lowering the activation energy and increasing the reaction rate.

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.
