Neurotransmitters act by binding to receptors that are

B) located in the cytoplasm.
C) tyrosine-kinase receptors.
D) not coupled to G proteins.

Question

Quizplus · Accepted Answer

Neurotransmitters act by binding to receptors that are ligand-gated ion channels. This means that when the neurotransmitter binds to the receptor, it causes the ion channel to open or close, allowing ions to flow in or out of the cell. This change in ion concentration can lead to changes in the neural activity and ultimately affect behavior and physiology. The other options, such as cytoplasmic receptors or tyrosine-kinase receptors, are not typically involved in neurotransmitter signaling.
