If a pharmaceutical company develops a new drug that acts as an agonist to a G-protein coupled receptor (GPCR) in pancreatic beta cells, which consequence follows?

💡 Explanation

GPCR agonists enhance receptor signaling, leading to increased intracellular signaling cascades that stimulate insulin release. Because activation of the receptor amplifies the normal insulin production pathway, insulin secretion increases; rather than decreasing glucagon, affecting glycogenolysis, or directly upregulating GLUT4 in muscle.
