Acetylcholine broken down is the process by which this neurotransmitter activates a suitable ligand-receptor to trigger a cell signaling pathway.
<h3>What is Acetylcholine?</h3>

Acetylcholine broken down is due to its hydrolysis, which ends cell signaling between brain synapses.
In conclusion, Acetylcholine broken down is the process by which this neurotransmitter activates a suitable ligand-receptor to trigger a cell signaling pathway.
