Adrenergic receptors

Which of the following second messenger pathways is characteristic of $\\\\beta$ adrenergic receptors ($\\\\beta_1$, $\\\\beta_2$, $\\\\beta_3$)? *

Stimulation of which adrenergic receptor subtype is most closely associated with the inhibition of adenylyl cyclase, resulting in decreased cyclic AMP ($\\\\text{cAMP}$) levels? *

A drug that acts as a selective antagonist at $\\\\alpha_1$ receptors would most likely cause which immediate effect? *

Which class of adrenergic receptors is primarily coupled to the Gq protein, leading to increased intracellular $\\\\text{IP}_3$ and $\\\\text{DAG}$? *

Which receptor subtype is primarily responsible for increasing heart rate (positive chronotropy) and contractility (positive inotropy)? *

In the context of adrenergic receptor classification, what is the primary difference between $\\\\alpha$ and $\\\\beta$ receptors regarding their coupling mechanism? *

Activation of $\\\\alpha_1$ receptors in vascular smooth muscle typically results in which physiological effect? *

Which adrenergic receptor subtype is primarily involved in mediating lipolysis in adipose tissue? *

Which adrenergic receptor subtype is selectively stimulated by low concentrations of epinephrine and is often located pre-synaptically to inhibit further neurotransmitter release? *

Which adrenergic receptor subtype is predominantly found in the smooth muscle of the bronchioles and mediates bronchodilation upon activation? *
