A peptide hormone involved in controlling glucose levels in the blood, they do this by promoting the breakdown of glycogen into glucose. Glucagon is produced by alpha cells in the islets of Langerhans.

 It is a peptide hormone, produced by alpha cells of the pancreas. It works with other hormones such as insulin to control glucose levels in the blood.

Glucagon is a hormone released by alpha cells in the islets of langerhan in the pancreas when blood glucose levels are low. It acts as a secondary messengers model along with adrenaline in order to stimulate glycogenolysis, gluconeogenisis and decrease rates of respiration in order to increase blood glucose levels

glucagon is a hormone produce by the alpha cells in the pancreas. It breaks down glycogen into glucose to increase glucose levels in the body when it is too low.

It is a peptide hormone, produced by alpha cells of the pancreas. When your blood glucose levels are low, the body can convert glycogen back into glucose and secrete it back into the blood stream, the hormone involved in this complex process is glucagon. The decrease in blood glucose levels is detected by the alpha and beta cells in the pancreas. After glycogen is converted into glucose, it can be used in cellular respiration.

Glucagon is involved in a negative feedback loop for low blood glucose concentration.

You will also come across the hormone insulin when studying glucagon.

Glucose is converted to glucagon when the body has high blood glucose concentrations (particularly after a meal) . This glucagon can later be broken down back to glucose via the assistance of enzymes (gluconeogenesis)

Glucagon is a hormone that stimulates and regulates blood sugar in the liver, breaks down glycogen (sugar) to release into the blood as glucose, it also breaks down amino acids and triglycerides (fat) into glucose for fuel for the body.

Glucagon is a peptide hormone produced by alpha cells in the pancreas. This hormone increases glucose and fatty acid levels in the bloodstream and is considered to be the body's chief catabolic hormone.

Glucagon is a hormone that is secreted by the pancreas in response to low blood glucose concentration. It raises blood glucose concentration by breaking down glycogen (which is a glucose storage molecule) found in the liver into glucose.

Glucagon is a hormone that regulates your blood sugar levels.

Glucagon is the antagonistic hormone for insulin. It is a peptide hormone which is secreted by alpha cells in the pancreatic islets. Low levels of glucose in the blood act as a trigger for glucagon release and it acts on its receptors which are found on liver and muscle cells. One of the actions of this hormone is to break down glycogen stores in the liver and muscles to raise blood glucose levels.

Glucagon is a hormone formed in the pancreas which promotes the breakdown of glycogen to glucose in the liver.

Glucagon is a peptide hormone released from pancreatic alpha cells in response to low blood glucose levels. It inhibits insulin (hormone produced by pancreatic beta cells) which wants to move glucose out of the blood into the cells, which would only serve to further decrease blood glucose levels. It also stimulates hepatic gluconeogenesis (synthesis of glucose by the liver) and glycogenolysis (breaking down glycogen to create more glucose, occurring in muscle and liver cells).

Glucagon is a hormone that is used to convert glycogen to glucose using the second messenger model.
