A. E1 binds to its substrate with higher affinity than E2
B. The velocity of reactions catalyzed by E1 and E2 at their respective saturating substrate concentrations could be equal, if concentration of E2 used is 10 times that of E1
C. The velocity of E1 catalyzed reaction is always greater than that of E2
D. The velocity of E1 catalyzed reaction at a particular enzyme concentration and saturating substrate concentration is lower than that of E2 catalyzed reaction under the same conditions
Answer» C. The velocity of E1 catalyzed reaction is always greater than that of E2
