high & low blood sugars, respectively
Glucose
Insulin and Glucagon
Yes insulin and glucagon are antagonistic hormones, as they antagonize, or incite a reaction, the liver into transforming glucose into glycogen when the blood sugar levels are high (insulin), and transforming glycogen into glucose when the blood sugar levels are low (glucagon).
The hormone from the pancreas which functions in opposition to insulin is glucagon. It raises blood sugar levels by promoting the breakdown of glycogen into glucose in the liver.
Insulin is secreted by the pancreas to control blood sugar levels.

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.
Insulin
Glucocoricoid
The hormone Insulin regulates the body's glucose levels.
The pancreas releases two hormones, insulin and glucagon. When blood sugar is high, insulin is released to promote uptake of glucose into the body's cells. Oppositely, when blood sugar is low, glucagon is released to stimulate breakdown of glycogen which is the body's store of sugar in the liver to raise blood glucose levels.
glucagon
Glucagon, just like insulin, does regulate blood glucose level. While insulin helps to decrease blood glucose level, glucagon initiate raising low levels. Raising blood glucose level becomes vital, as severe hypoglycaemia (very low level) can be fatal. If it occurs, - which can be due to certain drugs, medications, even diabetic medications, or improper dosage of insulin for diabetic patients, too vigorous and prolonged exercise, starving, etc -, glucagon injection can be a lifesaver. These two hormones, glucagon and insulin, are very important blood glucose concentration regulators.
