19.Enzyme A can act on substrate S and substrate T and follows simple MichaelisMenten kinetics. The Michaelis constant Km of enzyme A for substrate S is KmS =2 mM, and the rate constant ks is 5X103 sec¹. For substrate T, KmT = 5 mM, and
kT is 2.5X104 sec¹. Which substrate exhibits greater catalytic efficiency?
(A) S
(B) T
(C) Enzyme A uses S and T with the same catalytic efficiency.
(D) cannot be determined due to insufficient information.
(E) The result would change if the enzyme's conditions or substrate concentrations varied.
