A) Coenzymes increase the catalytic activity of enzyme
B) Catalyst does not initiate any reaction
C) The value of equilibrium constant is changed in the presence of a catalyst in the reaction at equilibrium
D) Enzymes catalyse mainly bio-chemical reactions
Correct Answer: C
Solution :
A catalyst decreases activation energies of both the forward and backward reaction by same amount, therefore, it speeds up both forward and backward reaction by same rate. Equilibrium constant is therefore not affected by catalyst at a given temperature.
