Acetylcholine is a neurotransmitter that, when bound to its receptor, causes the receptor to open a channel that allows the flow of Na+ ions into neurons. When the Na+ ions begin to flow into the neuron, this change in the net charge across the neuronal cell membrane often triggers Ca2+ ion channels to open. In this scenario, the acetylcholine receptor would be acting as a channel, and the Ca2+ channels would be classified as voltage-gated; leaky ligand gated; voltage-gated symporter; antiporter None of the above. ion
