Web9 jan. 2024 · I would first reparameterize the Michaelis-Menten model to this: V = Vmax * (9 * [S]) / (K + 9 * [S]) Thus, if [S] equals K you get V = Vmax * 0.9, so K is then the desired critical value. You cannot simply use 0.9 * K with the original parameterization because there K is the substrate concentration that results in 0.5 * Vmax.
