Question

Many drugs, like morphine, valium, and nicotine, act by binding to:

(A) Receptors in the brain
(B) Enzymes in the liver
(C) Ribosomes in the cytoplasm
(D) Golgi apparatus in the cell

Answer 1

Drugs like morphine, valium, and nicotine act by binding to receptors in the brain, increasing the activity of neurotransmitters. GABA agonists, such as ethanol and barbiturates, promote the activity of GABA receptors in the brain.

Step-by-step explanation:

Many drugs, like morphine, valium, and nicotine, act by binding to receptors in the brain. These drugs are called agonists, which increase the activity of neurotransmitters. For example, GABA agonists, including ethanol, barbiturates, and benzodiazepines, promote the activity of GABA receptors in the brain, which has an inhibitory effect on cells.
