Because they have similar chemical structures, morphine is able to lock into receptor sites for
A) GABA.
B) serotonin.
C) dopamine.
D) endorphins.
Answer: D
Rationale: Endorphins are produced by the pituitary gland and the hypothalamus and function to reduce pain and induce feelings of pleasure. Morphine—a drug derived from the poppy plant—binds to endorphin receptors (the term endorphin translates to internal or endogenous morphine). Morphine molecules fit into the same receptor sites as endorphins, and therefore produce the same pain-killing and euphoric effects.
