biochemistry: how do noncompetitive, mixed, and uncompetitive inhibitors affect Km and Vmax?
Homework Answers
Answer=In non-competitive,the inhibitor binds to the enzyme at a site other than the active site.Inhibitor binding alters the enzyme's three dimensional configuration and blocks the reaction.Km remain same while Vmax decreases.
Mixed inhibitor is a type of non-competitive inhibition the binding of inhibitor with enzyme influences the binding of substrate with enzyme.Km can increase OR decrease while Vmax always decreases.
In uncompetitive,an inhibitor binds at a site distinct from the substrate.However,an uncompetitive inhibitor will bind only to the ES Complex.On the other hand non-competitive inhibitor binds to either free enzyme or the ES Complex.Km and Vmax both decreases.
