Question

Quizplus · Accepted Answer

The majority of types of adrenoceptors produce excitatory effects. Adrenoceptors, also known as adrenergic receptors, are a type of G protein-coupled receptor that binds to the neurotransmitters epinephrine and norepinephrine. There are two main types of adrenoceptors: alpha-adrenoceptors and beta-adrenoceptors. Most types of alpha and beta adrenoceptors produce excitatory effects, although some alpha adrenoceptors can also produce inhibitory effects.
