Acetylcholine receptors are best characterized as what type of channel? Acetylcholine receptors are best characterized as what type of channel? voltage-gated Na+-K+ channels chemically gated Na+-K+ channels voltage-gated Ca2+ channels chemically gated Ca2+ channels

Chemically gated Na+-K+ channels

Explanation:

The acetylcholine receptors are the receptors or ion channel proteins which are considered the transmembrane proteins. The acetylcholine receptors are of two types depending on the ligand which binds that is either nicotinic or either muscarinic receptors.

When the acetylcholine binds the receptor molecule, the ion channels open up and allows the passage of the sodium and potassium ios which depolarizes the membrane potential and generates the action potential in the neuron.

Thus, Chemically gated Na+-K+ channels is correct.

i believe it would be the lungs.
