They get realy sick
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.
Insulin
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.
Glucocoricoid
The hormone Insulin regulates the body's glucose levels.
high & low blood sugars, respectively
glucagon
The pancreatic beta islets produce insulin. Alfa cells produce glucagon. Insulin and glucogon produce a homeostatic method to produce normal blood glucose levels.
Insulin causes the uptake of glucose from your blood into your cells. In a healthy person when blood sugar levels go up, insulin is secreted by the pancreas which causes a decrease in blood sugar. When they fall, your pancreas secrets glucagon, which causes cells to release sugar into the blood stream.
The pancreas is responsible for regulating blood glucose levels through the production of insulin and glucagon.
