15. Which of the following statements is true for the enzymatically catalyzed reaction?
A. The activation energy of the reaction is lowered so that a larger proportion of the substrate qualifies to overcome it
B. Additional substrate molecules are energized to overcome the activation energy of the reaction
C. The activation energy of the reaction is increased, thus decreasing the likelihood that any substrate molecules will overcome it
D. The activation energy of the reaction is lowered so that a fewer substrate molecule can overcome it
