An example of ligand-gated ion channels is ________.
A) the spreading of action potentials in the heart
B) acetylcholine receptors at the neuromuscular junction
C) K+ leakage channels
D) action potentials on the axon
E) second-messenger systems that activate postsynaptic neurons

Question

Quizplus · Accepted Answer

Acetylcholine receptors at the neuromuscular junction are an example of ligand-gated ion channels. When acetylcholine binds to these receptors, they open up and allow ions to flow through, triggering muscle contraction. The other answer choices do not involve ligand-gated ion channels.

An Example of Ligand-Gated Ion Channels Is ________
