Which of the following statements is TRUE about enzyme-catalyzed reactions?
A) The reaction is faster than the same reaction in the absence of the enzyme.
B) The free-energy change of the reaction is opposite from the reaction that occurs in the absence of the enzyme.
C) An enzyme catalyzes a reaction by raising the activation energy.
D) Enzyme-catalyzed reactions require energy to activate the enzyme.
E) Enzyme-catalyzed reactions release more free energy than noncatalyzed reactions.

Question

Quizplus · Accepted Answer

Enzyme-catalyzed reactions are faster than the same reaction in the absence of the enzyme. This is because enzymes lower the activation energy required for the reaction to occur, allowing the reaction to proceed more quickly.
