1.the benefit of measuring the initial rate of a reaction Vo is that at the
beginning of a reaction :
A.<ES> can be measured accurately.
B.change in <S>are negligible,so <S> can be treated as a constant.
C.change in<Km>are negligible,so Km can be treated as a constant.
D.Vo-Vmax.
E.varying <S> has no effect on Vo.
2.the following data were obtained in study of enzyme known to follow
Michaelis-Menten Kinetics:
Vo<mol/min> substrate added<mmol/L>
217 0.8
325 2
433 4
488 6
647 1000
the Km for this enzyme is approximately
A.1mM
B.1000mM
C.2mM
D.4mM
E.6mM
