Draw and label concentration -response plots on the same graph representing the effects of:

a) increasing concentration of an agonist label A

b) increasing concentration of an agonist A, in presence of a fixed concentration of a competitive antagonist B (label A+B)

C) increasing concentration of an agonist in the presence of a fixed concentration of a noncompetitive antagonist C (label A + C)

D) increasing concentrations of partial agonist D (label D) that is more potent than A

E) increasing concentrations of partial agonist E (label E) that is less potent than A
