Quizplus · Accepted Answer

The activation energy for the enzyme-catalyzed reaction is represented by the difference between the energy of the reactants and the energy of the transition state in the presence of the enzyme. In the figure, the energy of the transition state with the enzyme is shown as the peak of the curve labeled "B." Therefore, choice B represents the activation energy required for the enzyme-catalyzed reaction.
