    An allosteric inhibitor of the enzyme acts by binding to the

    A)  substrate

    B)  product

    C)  catalytic site of the enzyme

    D)  non-catalytic site of the enzyme

    Correct Answer: D

    Solution :

     The activity of certain enzymes, i.e. allosteric enzymes is regulated by compounds, which are not their substrates and which bind to the enzyme at specific sites away from the catalytic site. They modify enzyme activity by producing a reversible change in the structure of the enzymes catalytic site. Allosteric inhibitors slow down the reaction rate by binding to the non-catalytic site of the enzyme.
