WebKittens are actually more fragile than they appear, and problems can arise quickly. The big three things that I see are hypothermia, or low body temperature, hypoglycemia, or low … WebAs you can see, Km, then, is a function of both Kd/Ka and kcat, since a Michaelis-Menten enzyme both has to 1. bind the substrate and 2. catalyze the reaction. Km takes into account that enzyme-ligand complexes can react to form products, and so adjusts for enzyme binding AND reacting.
