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. Period. – AliceD ♦ Jan 25, 2015 at 14:47 WebBoth the inhibitor and the substrate do not stick on the enzyme for ever. The higher its affinity is the longer it stays. The inhibitor can be replaced by a higher substrate concentration.
