A receptor can directly open a channel and thereby exert a(n)____ effect,or it can produce slower but longer ____ effects.​
A)gated; metabotropic
B)​ionotropic; gated
C)​metabotropic; ionotropic
D)ionotropic; metabotropic

Quizplus · Accepted Answer

Ionotropic receptors directly open ion channels for rapid but short-lived effects, while metabotropic receptors produce longer-lasting effects through a complex signaling process that involves intracellular second messengers.
