Final answer:
Amylin is the hormone co-secreted with insulin that increases satiety and suppresses glucagon secretion. It helps to maintain glucose homeostasis along with insulin, which is secreted by the pancreas. Somatostatin is another pancreatic hormone that inhibits the secretion of both insulin and glucagon.
Step-by-step explanation:
The hormone amylin, which is co-secreted with insulin, is known to increase satiety and suppress the secretion of glucagon. Amylin acts on the brain to give a sensation of fullness, hence reducing food intake. It also inhibits glucagon secretion, thus preventing the liver from releasing too much glucose into the blood.
Glucagon, on the other hand, is a peptide hormone secreted by the alpha cells of the islets of Langerhans in the pancreas. It has effects that counter the actions of insulin. For instance, glucagon promotes the conversion of stored glycogen to glucose, leading to an increase in blood glucose levels. These two hormones work in tandem to maintain glucose homeostasis within the body.
Somatostatin is another endocrine hormone produced by the pancreas that plays a role in glucose regulation by inhibiting the production of growth hormone by the pituitary and the secretion of insulin and glucagon by the pancreas. It's not the hormone secreted with insulin, but it is important in the complex regulation of the body's energy resources.
