The equation is expressed as: v = (Vmax[S]) / (Km + [S]), where:
v: Reaction rate Vmax: Maximum rate of the reaction [S]: Substrate concentration Km: Michaelis constant, indicating the substrate concentration at which the reaction rate is half of Vmax
These components allow toxicologists to predict how quickly and efficiently a toxin is metabolized, which is crucial for assessing risk and potential biological effects.
