membrane receptor?
A. Ligand-gated ion channel
B. G-protein-coupled receptor
C. Receptor tyrosine kinase
D. Nuclear hormone receptor
E. Cytokine receptor
ANS: B. The majority of drugs available act on G-protein-coupled receptors.
2. Nalbuphine is an effective pain reliever because of its activity at mu-opioid receptors.
