When a neurotransmitter like acetylcholine is acting in an excitatory manner which of the following is likely a result of the acetylcholine acting on the postsynaptic cell?
A) Chemically gated sodium channels will open.
B) Chemically gated sodium channels will be closed.
C) Chemically gated potassium channels will open.
D) Chemically gated chloride channels will open.

Quizplus · Accepted Answer

When a neurotransmitter like acetylcholine acts in an excitatory manner, it generally leads to depolarization of the postsynaptic cell. This is achieved by the opening of chemically gated sodium channels, allowing sodium ions to flow into the postsynaptic cell, leading to depolarization. Therefore, choice A is the best answer.
