what do alpha and beta cells do in the pancreas?

Alpha cells make and release insulin, this acts to increase glucose uptake into muscle and fat cells, also promotes the storage of glucose as glycogen. Insulin is released in response to high blood glucose.
Beta cells make and release glucagon in response to low glucose levels or the presence of insulin. Glucagon promotes the breakdown of glycogen to release glucose and also promotes the breakdown of fats and proteins to release substrates for glucose formation.

The bulk of the pancreas is an exocrine gland secreting pancreatic fluid into the duodenum after a meal. However, scattered through the pancreas are several hundred thousand clusters of cells called islets of Langerhans.

The islets are endocrine tissue containing four types of cells. In order of abundance, they are the:
• beta cells, which secrete insulin and amylin
• alpha cells, which secrete glucagon;
• delta cells, which secrete somatostatin
• gamma cells, which secrete a polypeptide of unknown function.

Beta Cells
Beta cells have channels in their plasma membrane that serve as glucose detectors. Beta cells secrete insulin in response to a rising level of circulating glucose ("blood sugar").

Alpha Cells
The alpha cells of the islets secrete glucagon which acts principally on the liver where it stimulates the conversion of:
• glycogen into glucose ("glycogenolysis")
• fat and protein into intermediate metabolites that are ultimately converted into glucose.

In both cases, the glucose is deposited in the blood. Glucagon secretion is:
• stimulated by low levels of glucose in the blood
• inhibited by high levels of glucose in the blood
• inhibited by amylin.

The physiological significance of this is that glucagon functions to maintain a steady level of blood sugar level between meals.

Beta cells make and release insulin and Alpha cells secrete glucagon. Glucagon is a hormone that breaks down glycogen (stored in the liver) into glucose.
