Question

All the following statements concerning transmitter-gated ion channels are true EXCEPT:

Answer 1

Answer:

(b) Are Voltage-gated channels

Explanation:

Transmitter gates ion channels are also called ionotropic neurotransmitter receptors as one or more parts of the ion channel serve as a receptor for specific neurotransmitters.

Binding of the specific neurotransmitter to the receptor stimulates the opening of the ion channels and allows the transmembrane transport of specific ion.

The voltage-gated ion channels are the ones that open and close in response to changes in the voltage across the plasma membrane.

For example, voltage-gated Na+ channels are opened in response to depolarization of the membrane only.
