Allosteric regulation Explanation

Allosteric regulation is basically the regulation of an enzyme by binding an effector molecule at a site other than the enzyme's active site. Allosteric site is where this molecule actually binds and is also called the regulatory site. It is basically the increase in an enzymes activity that occurs when an allosteric activator binds to its specific regulatory site on the enzyme. The active site changes shape when an inhibitor binds to an allosteric site.
