Study of drug-receptor interaction has now shown that:
A. Maximal response occurs only when all receptors are occupied by the drug
B. Drugs exert an ‘all or none’ action on a receptor
C. Receptor and drugs acting on it have rigid
complementary ‘lock and key’ structural features
D. Properties of ‘affinity’ and ‘intrinsic activity’ are
independently variable
