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 WebMay 2, 2024 · $\begingroup$ I have edited your question to remove the erroneous description of affinity, corrected in the comment and tightened the wording. I have changed the title to reflect the actual question. I have removed reference to Km because 1) transporters are not enzymes and do not have Kms 2) Km is a parameter that is … WebThe binding constant, or affinity constant/association constant, is a special case of the equilibrium constantK, and is the inverse of the dissociation constant. R + L ⇌ RL The reaction is characterized by the on-rate constant konand the off-rate constant koff, which have units of M−1 s−1and s−1, respectively. himym crooked apartment episode
