when a molecule of a neurotransmitter
binds with a postsynaptic receptor.

Question 3

Answer 3

A receptor that contains a binding
site for a neurotransmitter and an ion
channel that opens when a molecule
of the neurotransmitter attaches to the
binding site

Question 4

Metabotropic Receptor

Answer 4

A receptor that contains a binding site for a neurotransmitter; activates
