Question

What is the DIFFERENCE between an allosteric inhibitor and a competitive inhibitor?

An allosteric inhibitor bound to one subunit alters substrate binding to other subunits; a competitive inhibitor bound at one active site alters binding at only that active site.

Allosteric inhibitors act only on multisubunit enzymes; competitive inhibitors act only on monomeric enzymes.

Competitive inhibitors are substrate analogs; allosteric inhibitors are transition state analogs.

A competitive inhibitor reduces Vmax; an allosteric inhibitor does not affect Vmax.

An allosteric inhibitor bound to one subunit alters substrate binding to other subunits; a competitive inhibitor bound at one active site alters binding at only that active site.

Explanation / Answer

An allosteric inhibitor bound to one subunit alters substrate binding to other subunits; a competitive inhibitor bound at one active site alters binding at only that active site.
