Quizplus · Accepted Answer

Olfactory receptors are metabotropic receptors, meaning that they do not directly cause ion channels to open or close. In contrast, touch, stretch, pressure, heat, and cold receptors are all examples of ionotropic receptors, which directly control the flow of ions across the membrane in response to their stimuli.
