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 answers 1.B 2.C THANKS A LOT --
