Question
Which one of the following is a ligand-gated ion channel?a.Muscarinic receptorsb.Thyroxine receptorsc.Nicotinic receptorsd.Insulin receptors
Solution
The answer is c. Nicotinic receptors. These are a type of receptor that can open an ion channel when bound by a ligand (in this case, nicotine or acetylcholine). This allows ions to pass through the membrane and into the cell, which can trigger a variety of cellular responses.
