WebThe Michaelis constant, Km, is often spoken of as if it were a measure of the affinity of the enzyme for the substrate: the lower the Km, the higher the binding affinity. This would be true if Km were the same as Kd (the equilibrium constant for the dissociation reaction), but it is not. For an enzyme-catalyzed reaction A.

WebNo, affinity reflects bonding. Km is measured using Vmax, but the absolute value of Vmax is totally irrelevant for Km. It merely reflects 0.5vmax, whatever the absolute value of Vmax. You are coupling Km and Vmax, while in reality Km says nothing about speed or product. It says something about substrate.
