Michaelis-Menten kinetics

Term · Chemistry · MLC-T-CHM-007300

A model describing the rate of enzyme-catalyzed reactions, relating reaction rate to the concentration of a substrate. It assumes the formation of an enzyme-substrate complex as an intermediate step. The model is characterized by two key parameters: the maximum reaction rate (Vmax) and the Michaelis constant (Km).
