A neuron with nicotinic receptors is exposed to acetylcholine. This will lead to
A) activation of chemically gated ion channels.
B) excitation of the neuron.
C) entry of sodium ion.
D) all of the above
E) none of the above

Question

Quizplus · Accepted Answer

When a neuron with nicotinic receptors is exposed to acetylcholine, it will bind to and activate the chemically gated ion channels associated with the receptor. This will result in the entry of sodium ions, which will depolarize the neuron and result in excitation. Therefore, all of the above choices (activation of ion channels, excitation of the neuron, and entry of sodium ions) are correct.
