WebExamples of Anti-competitive Inhibition ANTI-COMPETITIVE (nncompetitive) inhibition, in which the inhibitor combines with enzyme ... In competitive inhibition of enzyme catalysis, binding of an inhibitor prevents binding of the target molecule of the enzyme, also known as the substrate. This is accomplished by blocking the binding site of the substrate – the active site – by some means.
