![The Michaelis-Menten equation models the hyperbolic relationship between [S] and the initial reaction rate Vo for an
enzyme-catalyzed, single-substrate reaction E + S = ES → E + P. The model can be more readily understood when
comparing three conditions: [S] << Km, [S] = Km, and [S] >> Km-
Match each statement with the condition that it describes.
Note that "rate" refers to initial velocity Vo where steady state conditions are assumed. [Etotal] refers to the total enzyme
concentration and [Efree] refers to the concentration of free enzyme.
[S] << Km
[S]:
= Km
[S] >> Km
Not true for any of these

[ES] is much lower than [Efree].
[Efree] is about equal to [Eotal].
