試題詳解

(A) The V_max of a reaction can be attained at saturated concentration of substrate, even in the presence of a competitive inhibitor. 

(B) At saturating levels of substrate, the rate of an enzyme-catalyzed reaction is proportional to the enzyme concentration. 

(C) The rate of a reaction decreases steadily with time as substrate is depleted. 

(D) The Michaelis-Menten constant K_m equals the [S] at which v = 1/2 V_max. 

(E) The activation energy for the catalyzed reaction is the same as for the uncatalyzed reaction, but the equilibrium constant is more favorable in the enzyme-catalyzed reaction.
