Question

multiple choice question
what will trigger the opening of chemically gated ion channels?
-
o conversion of atp to adp in the postsynaptic cell
o binding of neurotransmitter molecules
o changes in membrane potential

Explanation:

Chemically - gated ion channels open when neurotransmitter molecules bind to them. ATP - ADP conversion in the postsynaptic cell is not related to the opening of these channels. Changes in membrane potential trigger voltage - gated ion channels, not chemically - gated ones.

Answer:

Binding of neurotransmitter molecules
