Ionotropic receptors are similar to voltage-gated ion channels except that:
A) the ion channels are opened when a neurotransmitters binds to the receptor.
B) there is not an ion channel.
C) hyperpolization opens the receptor channels.
D) neurotransmitters pass through the channel instead of ions.

Question

Quizplus · Accepted Answer

Ionotropic receptors are activated by the binding of a neurotransmitter to the receptor, which causes the ion channel to open, allowing ions to pass through and depolarize the membrane potential. This is similar to voltage-gated ion channels, but the activation mechanism is different.
