Q1:

Which of the following statements is true for 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 molecules can overcome it

ANS:A - The activation energy of the reaction is lowered so that a larger proportion of the substrate qualifies to overcome it
