Once the data is collected, it is plotted on a graph. The x-axis usually represents the substrate concentration, while the y-axis represents the reaction rate. This plot is known as a Michaelis-Menten plot, characterized by a hyperbolic curve that levels off at high substrate concentrations. This curve indicates that the enzyme becomes saturated with substrate, leading to a constant reaction rate.

To determine Vmax and Km more accurately, researchers often use double-reciprocal plots, such as the Lineweaver-Burk plot. This plot involves taking the reciprocal of both the substrate concentration and the reaction rate, resulting in a linear plot. The y-intercept of this plot gives the inverse of Vmax, while the x-intercept gives the inverse of Km.
