A The reaction is faster than the same reaction in the absence of the enzyme. Which of the following statements is true about most enzyme-assisted reactions. Enzymes are quickly used up during the reactions.

However some key steps require separate enzymes for the reverse step in order to provide for independent regulation of anabolic and catabolic pathways. The activation energy for the catalyzed reaction is the same as for the uncatalyzed reaction but the equilibrium constant is. Enzymes change the Key for chemical reactions d.
