An Example of Ligand-Gated Ion Channels Is

Question

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) cAMP-dependent protein kinases.
D) action potentials on the axon.
E) graded hyperpolarization.

Accepted Answer

Acetylcholine receptors at the neuromuscular junction are an example of ligand-gated ion channels, as they open in response to binding of the neurotransmitter acetylcholine.
