WebSubstitution of v max (eq. 3) for k 2[E] 0 (eq. 2) yields the familiar two-parameter Michaelis-Menten equation that is the basis for this experiment: (5) Equation 5 shows the experimentally observable v 0 as a function of the initial substrate concentration [S] 0 and the two parameters v max and K m. If experimental data for v 0 and [S] 0 are Web1 Answer. Since the Michaelis-Menton constant Km is the concentration of substrate at 0.5Vmax, it is an inverse measure of its substrate affinity, because a lower Km indicates that less substrate is needed to reach a certain reaction speed. Hence, a low Km means a high substrate affinity. "Maybe the maximum velocity (Vmax) of higher-Km enzymes ...
