Question
Chapter 22, Problem 75P
Interpretation Introduction
Interpretation:
An explanation corresponding to the given statement that the enzyme catalyzes the forward reaction but not the backward reaction for its substrate-product pair(s) is to be stated.
Concept Introduction:
The biological catalysts which lower the minimum amount of energy required by the reactants to convert into product are known as enzymes. An enzyme does not alter the potential energy of reactant and product.

An uncatalyzed reaction has an equilibrium constant, Keq, of 50. In the presence of an appropriate enzyme, the forward rate of the reaction increased by 20-fold. What is the equilibrium constant in the presence of the enzyme?
Which statement does NOT apply to the lock-and-key theory?
O explains the functioning of enzymes
explains the need for a specific three dimensional structure found in proteins
