Web22 de jan. de 2013 · "Km is the inverse of the enzymes affinity", or think of it as the enzymes K^-1 This would imply that an enzyme with a high K value, or high affinity would have a low value. If K=5 then Km=1/5 . Best explanation I can come up with after being out of the class for 1 year, this part of Biochemistry sucked. WebThe concept of “high- and low-affinity K + transport” got more cracks in the analysis of the dependency of the K + fluxes on the external proton concentration. In contrast to the proton-coupled K + transport via the K + /H + co-transporter, the flux through the K + channel should actually be independent of [ H+] ext.
