<P> In biology , the active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction . The active site consists of residues that form temporary bonds with the substrate ( binding site ) and residues that catalyse a reaction of that substrate ( catalytic site ) . The active site is usually a groove or pocket of the enzyme which can be located in a deep tunnel within the enzyme , or between the interfaces of multimeric enzymes . An active site can catalyse a reaction repeatedly as its residues are not altered at the end of the reaction ( they may change during the reaction , but are regenerated by the end ) . </P>
