What are allosteric inhibitors?

Explanation

Compounds which modify enzyme activity by causing a reversible change in the structure of the enzyme active site. This in turn affects the ability of the substrate to bind to the enzyme. Such compounds are called allosteric inhibitors. E.g. the enzyme hexokinase which catalysis glucose to glucose-6 phosphate in glycolysis is inhibited by glucose-6 phosphate. this is an example for feedback allosteric inhibitor.
