Adrenergic receptor subtypes are

Question

Quizplus · Accepted Answer

Adrenergic receptor subtypes are primarily metabotropic, meaning they exert their effects on the cell through second messenger systems, such as cAMP. There are two main types of adrenergic receptors: alpha and beta, and each type has different subtypes. Most alpha receptors are metabotropic and can be further divided into subtypes, such as alpha-1 and alpha-2. Similarly, most beta receptors are also metabotropic and can be divided into subtypes, such as beta-1, beta-2, and beta-3.
