WebIn noncompetitive inhibition, an inhibitor molecule binds to the enzyme at a location other than the active site (an allosteric site). The substrate can still bind to the enzyme, but the inhibitor changes the shape of the enzyme so it is no … WebCHE 341 Lab 6 - Tyrosinase Inhibition by Justin Maresh.

The inhibitor dissociation constant may differ between E and ES (i.e. KI ≠ KIu ). The special case where KI = KIu goes by the name noncompetitive inhibition. Note that in this case, KM is not affected, while Vmax is … WebMixed inhibition is a type of enzyme inhibition in which the inhibitor may bind to the enzyme whether or not the enzyme has already bound the substrate. It does, however, have a greater affinity for one state or the other. It is called “mixed” because it can be seen as a conceptual “mixture” of competitive inhibition and uncompetitive inhibition. clipart of stress
