Which of the following channels open in response to an extracellular stimulus such as a neurotransmitter?

Question

Quizplus · Accepted Answer

Ligand-gated channels, also known as ionotropic receptors, open in response to an extracellular stimulus such as a neurotransmitter binding to the receptor. Mechanoselective channels respond to mechanical stimuli such as pressure or tension, signal-gated channels respond to intracellular signals, and voltage-gated channels respond to changes in membrane potential. Therefore, the best choice is B, as it is specific to extracellular stimulation by a ligand.
