Question

Binding of acetylcholine to the nicotinic receptor allows which

ion(s) to flow across the muscle cell membrane through the receptor
channel?

Answer 1

When acetylcholine binds to the nicotinic receptor, it allows sodium, calcium, and potassium ions to flow across the muscle cell membrane.

Step-by-step explanation:

The binding of acetylcholine to the nicotinic receptor allows cations of sodium, calcium, and potassium to flow across the muscle cell membrane through the receptor channel. These ions are important for depolarization and muscle contraction.
