What action does Acetylcholine have in a muscle cell?
A) opens voltage gated Na+ channels
B) opens receptor gated Na+ channels
C) opens mechanically gated Na+ channels

Respuesta :

Answer:

The answer is B: opens receptor galted NA+ channels

Explanation:

The action of acetylcholine in a muscle cell is to activate the sodium (Na +) channels through receptors. There are two types of acetylcholine receptors:

- Nicotinic or ionotropic receptor = The action on this receptor is excitatory.

- Muscarinic or metabrotopic receptor = The action on this receptor is inhibitory.
