Michaelis-Menten equation
The Michaelis-Menten equation describes how the rate of an enzyme-catalyzed reaction depends on the concentration of the substrate (the molecule the enzyme acts on). It shows that at low substrate levels, the reaction rate increases rapidly with more substrate. However, as substrate levels continue to rise, the enzyme becomes saturated, and the reaction rate levels off, reaching a maximum – called Vmax. The equation helps us understand enzyme efficiency and how quickly reactions occur, with key parameters like the substrate concentration at half-maximum rate (Km) indicating enzyme affinity. It’s a fundamental tool in biochemistry to model enzyme activity.
