In the nervous system neurotransmitters such as acetylcholine are released at synapses
between nerve cells. When the neurotransmitters bind to a receiving cell ions flow into the cell
triggering an electrical signal to be released sending an action potential across nerve cells. This
is an example of:
A. A G-protein-coupled receptor
B. A ligand-gated ion channel receptor
C. A Tyrosine Kinase receptor
D. Adenylyl cyclase receptor
