      Which site of an enzyme is called allosteric site?                                                                                                [1]

    Answer:

      An enzymic site, distinct from the active site, which by binding molecules other than the substrate induces a conformational change which affects the enzymes activity is called allosteric centre. It can also be defined as Enzymes form only one stereoisomer because they possess achiral binding site. This chiral binding site is called allosteric centre. This site allows reagents to be delivered to only one side of the functional group.           [1]
