The Michaelis-Menten equation is often used to describe the kinetic characteristics of an enzyme-catalyzed reaction.
Vmax [S]
U =
Km + [S]
where v is the velocity, or rate, Vmax is the maximum velocity, Km is the Michaelis-Menten constant, and [S] is the
substrate concentration.
A graph of the Michaelis-Menten equation is a plot of a reaction's initial velocity (vo) at different substrate concentrations
([S]).
First, move the line labeled Vmax to a position that represents
the maximum velocity of the enzyme.
