D) vesicles.
E) receptor subtypes.

Question

Quizplus · Accepted Answer

Metabotropic receptors are coupled to signal proteins and G proteins, which then activate second messenger systems leading to intracellular effects. This is in contrast to ionotropic receptors, which are directly linked to ion channels and trigger rapid changes in membrane potential. The other choices are not directly related to metabotropic receptors.
