Psychological dependence

Question 22

Genetically determined abnormal response to normal doses of drugs

Answer 22

Pharmacogenetic disorder

Question 23

A specialized macromolecule that binds to the drug molecule, altering the function of the cell and producing the therapeutic response

Answer 23

Receptor

Question 24

A drug that alters cellular function can increase or decrease the physiologic functions of the cell

Answer 24

Alterations in Cellular Environment

Question 25

Drug that binds with a receptor to produce the therapeutic response

Answer 25
