Answer:

ligand; molecule; ligand; molecule; nervous system

Explanation:

Ligand-gated ion channels are membrane proteins that interact with ligands (molecules) and open in response to this binding. In the nervous system, these channels are activated by neurotransmitters (ligands) that regulate synaptic transmission between nerve cells (neurons). Neurotransmitters are signaling molecules clustered close to the cell membrane of axon terminals in presynaptic neurons. For example, glutamate is a ligand neurotransmitter that binds to ion channels and thus stimulates synaptic activity in the mammalian brain.
