Final answer:

Nicotinic receptors are ligand-gated channels that result in depolarization. They do not cause hyperpolarization. Subunits do not disassociate upon binding to ACh.

Explanation:

Nicotinic receptors are ligand-gated channels. When acetylcholine binds to these receptors, ion channels open allowing the influx of sodium and efflux of potassium, leading to depolarization.

Nicotinic receptors cause hyperpolarization of the postsynaptic cell. False statement. Nicotinic receptors actually cause depolarization and are always excitatory.

Nicotinic receptors have subunits inside the neuron that disassociate when binding to ACh occurs. False statement. Nicotinic receptors are located on the cell membrane and do not have subunits that disassociate when binding to ACh.
