ANSWER: The bonding site of competitive inhibitors is at the active site on the enzyme, while the bonding site of allosteric inhibitors is NOT at the active site of the enzyme.
EXPLANATION: Competitive inhibitors compete with other substrates by binding to the specific enzyme's active site so that the other substrate cannot bind to it (the competitive inhibitor and the substrate it competes with will have similar shapes that are complementary to the active site of the enzyme).
On the other hand, allosteric inhibitors bind to an area on the enzyme that is NOT the active site. This causes the enzyme to change its shape and therefore change the shape of its active site.
