The Michaelis-Menten Equation nicely describes the experimental observations.

This equation expresses the initial rate of reaction in terms of a measurable quantity, the initial substrate concentration. The two kinetic parameters, V max and K m , will be different for every enzyme-substrate pair. . When [S] >> K m. When [S] << K m.
