Glucagon, yes. Cortisol, probably not. Glucagon raises blood sugar. Many type one diabetics own glucagon injectors, so that when their blood sugar goes too low they (or someone with them) can inject them with glucagon. Cortisol does raise blood sugar, but it is not used to raise blood sugar. It's used to treat many other diseases, but not the low blood sugar which type 1 diabetics sometimes get.
Glycogenesis is stimulated by insulin in response to high glucose levels.
Glucagon, adrenaline, cortisol and growth hormone.
Glucagon, Epinephrine, Cortisol, (and Growth Hormone)
A
The pancreas (glucagon) and the adrenal glands (cortisol).
The main hormone resposible for raising blood sugar is Glucagon. However, in times of stress, other hormones such as Cortisol and adrenaline may also play a role.
Insulin, glucagon, epinephrin, cortisol, growth hormone, thyroxin, somatostatine and ACTH
There are several hormone which serve to raise blood glucose levels. Some examples include cortisol, epinephrine, glucagon, and growth hormone.
The main hormone that signals the release of glucose into the blood is Glucagon, however, it is used in conjunction with other hormones which also cause a release of glucose into the blood. These are somatostatin, Adrenaline (epinephrine for Americans), Cortisol and ACTH.
Glucagon is a hormone, I guess you meant "What gland secretes glucagon"The gland that secretes glucagon is PancreaThis hormone is absorbed by the body and turned into sugar to increase glucose in the blood. A blood glucose level below 80 is considered hypoglycemic and is very dangerous for diabetics, therefore must be treated with glucagon or glucagen.
The hormone that regulates blood glucose levels is insulin plus a second hormone, glucagon. Insulin lowers blood glucose levels and glucagon increases blood glucose levels. Insulin actually carries the glucose molecule across the cell membrane. That is how it actually lowers the glucose molecules in the blood. Glucagon causes the liver, which stores glycogen, to convert it to glucose which is released in the blood. These two hormones form a feedback mechanism which keeps glucose stable.
The alpha cells in the pancreatic islets produce glucagon themselves. It is released when blood glucose is too low. It is made by the usual process of protein transcription and translation from pertinent genes on the DNA.
