The Michaelis-Menten equation is often used to describe the kinetic characteristics of an enzyme-catalyzed reaction. Vmax [S] Km + [S] V = where u 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. Next, move the line labeled 1/2 Vmax to its correct position. Then, move the line labeled Km to its correct position. v (μM/min) 300 275 250 225 200 175 150 125 100 75 50 25 0 0 K m 10 20 30 V max 40 50 [S] (µM) 1/2 V max Michaelis Menten curve 60 70 80 90 100

The Michaelis-Menten equation is often used to describe the kinetic characteristics of an enzyme-catalyzed reaction.
Vmax [S]
Km + [S]
V =
where u 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.
Next, move the line labeled 1/2 Vmax to its correct position.
Then, move the line labeled Km to its correct position.
