Compare the effects of the neurotransmitters acetylcholine and serotonin on ion channels
What will be an ideal response?
Acetylcholine has a direct effect on ion channels through its binding to chemically gated ion channels. The effect of the neurotransmitter serotonin has an indirect effect on ion channels. It acts as a first messenger by binding to membrane receptors coupled with G proteins. The activated G protein produces or releases a second messenger that then affects ion channels, altering conditions or activities of the postsynaptic cell.
