Hi Orie


Glucagon is a hormone formed in the pancreas. It is released in response to low blood glucose levels which may occur after periods of exercise.

Glucagon has three main functions:

  • Stimulates the liver to break down glycogen into glucose, which is then released into the blood.
  • The breakdown of triglycerides into fatty acids.
  • The process of gluconeogenesis, this is the conversion of amino acids into glucose.

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 produced by alpha cells where it is released from the pancreas into the bloodstream. When blood glucose levels are low, glucagon is released and causes glycogenolysis to occur. This is where stored glycogen is converted back into glucose to increase glucose levels in the blood

Glucagon is a hormone that stimulates the breakdown of glycogen into glucose, increasing the blood-glucose concentration. It is produced in the Isle of Langerhans of the pancreas.

Glucagon is a natural hormone released from a gland called “pancreas”. Glucagon is released in response to a drop in blood sugar, prolonged fasting, exercise and when we eat protein-rich meals.

Function? : Glucagon helps blood sugar (glucose) rise back up, when it is low. It does this by triggering the Liver to convert “glycogen” (previously stored glucose) back into glucose to be used by the body. Also Glucagon helps the body make glucose from amino acids (units of proteins).

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 is used to convert glycogen to glucose using the second messenger model.

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.

Glucagon is one of a number of hormones responsible for glucose homeostasis - the maintenance of stable blood glucose levels in the body. In response to falling blood glucose levels, glucagon in released from alpha cells located in the pancreas. Glucagon travels through the bloodstream to the liver, where it attaches to receptors found on the cell membranes of hepatocytes (liver cells). What follows is a sequence of intracellular events, resulting in the breakdown of glycogen (the storage form of glucose) into glucose, which is released from the cell into the bloodstream. As a result, blood glucose levels rise and homeostasis is restored.

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.

 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.

Hi Orie,


A glucagon is a hormone that the pancreas produces when the blood sugar is low. It raises the glucose levels in the blood in order to give the body more energy.
