Question

An ion channel that opens when neurotransmitter binds to it is called a __________-gated channel.

Answer 1

An ion channel that opens when neurotransmitter binds to it is called a ligand-gated channel. Ligand-gated channel is a group of transmembrane ion channel proteins which open to allow the passage of ions such as Na+, K+ through the membrane upon activation by a specific chemical such as a neurotransmitter.

Answer 2

An ion channel that opens when neurotransmitter binds to it is called a Ligand-gated ion channel. These channels are also called ionotropic receptors; they open to allow ions such as potassium ions, sodium and calcium and/or chloride ions to pass through the membrane in response to the binding of a chemical messenger or a ligand (for example a neurotransmitter).
