Question:

Which one of the following statements is not correct?

Coenzymes increase the catalytic activity of enzyme

Catalyst does not initiate any reaction

The value of equilibrium constant is changed in the presence of a catalyst in the reaction at equilibrium

Enzymes catalyse mainly bio-chemical reactions

Solution:

The value of equilibrium constant is not changed in the presence of a catalyst in the reaction at equilibrium. The catalyst increases the rate of forward and reverse reaction to the same extent. It does not affect the value of the equilibrium constant.
