Correct Answer is A
Explanation
Rationale:
A. Insulin -Insulin is secreted by pancreatic beta cells and facilitates glucose uptake into muscle, fat and other tissues, lowering blood glucose levels.
B. Glucagon -Glucagon, produced by pancreatic alpha cells, acts primarily on the liver to stimulate the breakdown of stored glycogen (glycogenolysis) and the synthesis of new glucose from non-carbohydrate sources like amino acids (gluconeogenesis).
C.Amylin -Amylin is a hormone secreted with insulin from the beta cells. Its actions actually help lower blood glucose levels after a meal.
D.Somatostatin -The primary role of somatostatin (from pancreatic delta cells) in glucose regulation is to inhibit the secretion of both insulin and glucagon.
