Match up the correct receptor type and effect.
A) metabotropic; direct opening of an ion channel
B) ionotropic; more time required to open an ion channel
C) metabotropic; G protein activation leads to activation of a second-messenger
D) metabotropic; rapid opening of a single ion channel
E) metabotropic; rapid short-lived effects on ion channels

Question

Quizplus · Accepted Answer

Metabotropic receptors work through a mechanism involving G protein activation, which then leads to the activation of a second-messenger system. This process is more complex and indirect compared to the direct action of ionotropic receptors on ion channels.
