A.The enzyme donates its own free energy, converting an unfavorable reaction into a favorable one
B.The enzyme lowers the activation energy of the transition state equally for forward and reverse directions, changing rate but not free energy change
C.The enzyme raises the energy of the products, pulling the reaction toward completion
D.The enzyme steadily consumes substrate until only product remains in the vessel
