Quizplus · Accepted Answer

The activation energy required for an enzyme-catalyzed reaction is the difference between the energy of the reactants and the energy of the transition state. In Figure 6.4, the change in free-energy represented by b (the difference between the energy of the reactants and the peak of the energy barrier) corresponds to the activation energy required for the enzyme-catalyzed reaction.
