Question

The activity of a catalyst is due to the presence of active centres on it.

• A. True
• B. False

Answer 1

The correct option is A True

A catalyst is a substance which accelerates the rate of a chemical reaction without undergoing any change in its chemical composition or mass during the reaction. A catalyst accelerates the rate of a reaction by lowering the activation energy.

The activity of a catalyst is due to the presence of active centres on it.

The binding of a substrate to the active site of an enzyme is a very specific interaction.
