WebMixed inhibition is when the inhibitor binds to the enzyme at a location distinct from the substrate binding site. The binding of the inhibitor alters the KM and Vmax. Similar to … WebInhibitors does not have to bind to the active site in order to inhibit enzyme. If they are allosteric they bind some external site and change shape of enzyme - deform active site - which is now malfunctioned and unable to bind substrate. Well, if enzyme still works after methanol binding to it, it means that methanol is reversible inhibitor.
