Enzyme Activation | MCQs

Explanation

Activators are molecules that increase the activity of enzymes, often by binding to a specific site on the enzyme.

Inhibitors are molecules that decrease the activity of enzymes, often by binding to a specific site on the enzyme.

Explanation

A holoenzyme is the complete, active enzyme, formed when an apoenzyme (protein part) binds with its cofactor or coenzyme.

It consists of a polypeptide chain plus non-protein component, making it catalytically active.

Explanation

Catalase is most active around pH 7, which is neutral and reflects its optimal working conditions.
