The value of KM is inversely related to the affinity of the enzyme for its substrate. High values of KM correspond to low enzyme affinity for substrate (it takes more substrate to get to Vmax ). Low KM values for an enzyme correspond to high affinity for substrate. robert day osteopath reviews

What does a low Michaelis constant mean? [Ultimate Guide!]

WebDominique explains this very well. It is best to regard Km and Vmax as independent parameters arising from intrinsic properties of the enzyme. … WebThe size of Km tells us several things about a particular enzyme. A small Km indicates that the enzyme requires only a small amount of substrate to become saturated. Hence, the maximum velocity is reached at relatively low substrate concentrations. A large Km indicates the need for high substrate concentrations to achieve maximum reaction velocity. robert day photographyWebMar 5, 2024 · On the other hand Vmax/2 is a velocity and is nothing more than that.
