Which of the following statements regarding enzymes is true?
A)Enzymes increase the rate of a reaction by making the reaction more exergonic.
B)Enzymes increase the rate of a reaction by lowering the activation energy barrier.
C)Enzymes increase the rate of a reaction by reducing the rate of reverse reactions.
D)Enzymes change the equilibrium point of the reactions they catalyze.

Question

Quizplus · Accepted Answer

Enzymes lower the activation energy barrier, which allows for a higher proportion of reactant molecules to have enough kinetic energy to react and thus increases the rate of the reaction. Enzymes do not change the overall energy of the reaction or the equilibrium point.
