WebIn fact, the inhibitor and substrate don't affect one another's binding to the enzyme at all. However, when the inhibitor is bound, the enzyme cannot catalyze its reaction to produce a product. Thus, noncompetitive inhibition acts by reducing the number of functional enzyme molecules that can carry out a reaction.

Webinhibitor is binding to the same site as the substrate. So, as is the case with high KM, it is necessary to have more substrate to achieve a higher reaction rate, since the substrate can outcompete for the binding sites. 2.
