Question:
Beta 2 receptors act via following secondary messenger
Beta 2 receptors act via following secondary messenger
Show Hint
Beta-2 receptors are Gs-coupled GPCRs -- consider which enzyme is activated by the Gs protein.
Updated On: Jun 23, 2026
- Adenylate Cyclase
- Tyrosine kinase receptors
- TGF-beta receptors
- Cytokine receptors
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Beta-2 adrenergic receptors are Gs-coupled GPCRs. Agonist binding activates Gs, which stimulates Adenylate Cyclase (Adenylyl Cyclase) to convert ATP to cAMP. cAMP activates PKA, producing the cellular response (bronchodilation, smooth muscle relaxation, glycogenolysis).
Distractors:
- Tyrosine kinase receptors: insulin, EGF, PDGF
- TGF-beta receptors: serine/threonine kinase, SMAD pathway
- Cytokine receptors: JAK/STAT pathway
Beta-2 receptors act via Adenylate Cyclase (cAMP pathway).
