Neurotransmitters that bind ionotropic receptors control:
A)the movement of ions into or out of the postsynaptic neuron.
B)the formation of a second messenger inside the postsynaptic neuron.
C)the activation of G-proteins inside the postsynaptic neuron.
D)some metabolic process inside the postsynaptic neuron.

Question

Quizplus · Accepted Answer

Ionotropic receptors are directly coupled with ion channels, so when a neurotransmitter binds to an ionotropic receptor, it directly controls the movement of ions into or out of the postsynaptic neuron. This can lead to depolarization or hyperpolarization of the neuron, which can determine whether or not an action potential is generated. Neither second messengers, G-proteins, nor metabolic processes are directly affected by ionotropic receptors.
