推 felix1984:為啥有人會拿考古題來這個版.....然後我覺得第一題是b 01/17 01:08
推 dodo7444:恩, 第一題是B, 因為一開始[S]變化量極小,可視為constant 01/17 16:36

※ 引述《angela1221 (不想再醫院啦 真累 )》之銘言：
: 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.
是B沒錯~不要亂誤導別人...
: 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
除了第一組數據以外,其他的算起來Km~2mmol/L
