A competitive inhibitor is a molecule that: Preferentially binds to an enzyme at a site other than the active site Enhances the catalysis of an enzyme Binds to an enzyme and increases the bind strength of the substrate Binds to the active site and blocks the substrate More than one of the above.
Which answer best describes a drug which is an allosteric inhibitor? Select one: a. binds to the binding site for the endogenous ligand and have no physiological response b. increases the binding of the endogenous ligand C. competes with the endogenous ligand on the receptor binding site d. decreases the binding of the endogenous ligand
