Answer:
The rate of reaction when the enzyme is saturated with substrate is the maximum rate of reaction, Vmax. ... This is usually expressed as the Km (Michaelis constant) of the enzyme, an inverse measure of affinity. For practical purposes, Km is the concentration of substrate which permits the enzyme to achieve half Vmax.
