How do glucagon and insulin work together?

Answer 1

Insulin is secreted when blood sugar rises. It works by stimulating receptors on tissue cells to escort glucose into the cells. It all suppresses glucagon, hormone-sensitive lipase (a hormone responsible for mobilizing and using fat stores) and suppresses the appetite centers in the brain.

Glucagon is secreted when blood sugar is low. It triggers gluconeogenesis in the liver, which means that fats and proteins are converted into glucose and released into the blood. It also is responsible for mobilizing glycogen stores, suppresses insulin, and mobilizes fat stores.

So glucagon and insulin not only do opposite things, they are antagonistic to each other, meaning when one is high the other one is low. They do not technically work "together".

High levels of insulin are common in those who consume excessive calories and excessive carbohydrate foods. For those who are sensitive to the effects of insulin, this can cause reactive hypoglycemia and obesity.

Answer 2

These are two hormones produced by the Islets of Langerhans in the pancreas. When glucose levels are high in the blood, insulin converts glucose to glycogen for storage.
When the blood glucose levels are low, glucagon works in opposition to insulin and converts glycogen back to glucose.

Answer 3

These two hormones are both produced by the pancreas, and are both involved in the up-take of glucose by different organs. When you have just eaten a meal, levels of glucose are extremely high in the bloodstream. Insulin encourages the liver and muscles cells to absorb glucose and to convert it into the inslouble carbohydrate - glycogen. When the blood-sugar level in the blood is low, glucagon is released by the pancreas to help convert the glycogen back into glucose, and release it from the liver and muscles, into the blood. Consequently, homeostasis of blood-sugar levels is kept relatively constant.

Answer 4

Insulin and glucagon regulate the concentration of glucose in the blood. When the blood sugar is too high, insulin is released to trigger the absorption of glucose from the blood, to decrease the blood glucose concentration. When the blood glucose it too low, glucagon promotes the release of glucose into the blood. So, insulin and glucagon have an antagonistic relationship because although they are both responsible for returning the blood sugar to normal, insulin absorbs excess glucose while glucagon returns glucose to the blood when there is not enough.

Answer 5

Glucagon and insulin are hormones that work together to regulate blood glucose levels. Insulin helps lower blood sugar by promoting the uptake of glucose by cells, while glucagon raises blood sugar levels by promoting the breakdown of glycogen stores in the liver. This delicate balance allows the body to maintain a stable glucose level for energy production.
