Glucagon, secreted by the pancreas, promotes glycogen breakdown to release glucose into the bloodstream.
Ref: NCERT Class 11 Biology Chapter 19: Chemical Coordination and Integration Pancreas - Insulin Glucagon and Diabetes
Glucagon, secreted by pancreatic α-cells, increases blood glucose levels by stimulating glycogen breakdown in the liver.
Ref: NCERT Class 11 Biology Chapter 19: Chemical Coordination and Integration Pancreas - Insulin Glucagon and Diabetes
Glucagon is secreted by the alpha cells of the pancreas, not beta cells.

Cortisol, secreted by the adrenal cortex, plays a crucial role in the metabolism of carbohydrates, proteins, and fats.
Ref: NCERT Class 11 Biology Chapter 19: Chemical Coordination and Integration Adrenal Gland - Cortex and Medulla
Cortisol, a glucocorticoid secreted by the adrenal cortex, increases blood glucose levels by stimulating gluconeogenesis.

Both β-adrenergic receptors and glucagon receptors couple to the stimulatory G protein Gs. Activated Gs stimulates adenylyl cyclase, elevating cAMP and activating protein kinase A. PKA phosphorylates enzymes of glycogen metabolism, ultimately raising blood glucose. Insulin opposes these effects by promoting dephosphorylation of the same target proteins, illustrating reciprocal control of carbohydrate homeostasis.
