This category focuses on the pancreas’s endocrine functions, particularly insulin and glucagon, which regulate blood sugar levels. It includes questions on hormone secretion, glucose metabolism, and the physiological basis of diabetes.
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
Insulin, secreted by the beta cells of the pancreas, lowers blood glucose levels by promoting glucose uptake by cells.
Ref: NCERT Class 11 Biology Chapter 19: Chemical Coordination and Integration Pancreas - Insulin Glucagon and Diabetes
The pancreas secretes insulin from its beta cells, which regulates blood glucose levels.

Ghrelin, secreted by the stomach, stimulates hunger and increases food intake.
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.
