How glucose is regulated in the body?

The pancreas releases another hormone, glucagon, when the blood sugar levels fall. This causes the cells in the liver to turn glycogen back into glucose which can then be released into the blood. The blood sugar levels will then rise.
A.

What is blood glucose regulation?

Blood sugar regulation is the process by which the levels of blood sugar, primarily glucose, are maintained by the body within a narrow range. This tight regulation is referred to as glucose homeostasis.
B.

How glucose homeostasis is maintained?

Glucose Homeostasis: the balance of insulin and glucagon to maintain blood glucose. Insulin: secreted by the pancreas in response to elevated blood glucose following a meal.
C.

How does insulin and glucagon regulate blood sugar?

Glucagon works to counterbalance the actions of insulin. About four to six hours after you eat, the glucose levels in your blood decrease, triggering your pancreas to produce glucagon. This hormone signals your liver and muscle cells to change the stored glycogen back into glucose.
  • What does glucagon regulate?

    The pancreas releases glucagon when the concentration of insulin (and indirectly glucose) in the bloodstream falls too low. Glucagon causes the liver to convert stored glycogen into glucose, which is released into the bloodstream. High blood-glucose levels, on the other hand, stimulate the release of insulin.

  • How does insulin bind to a cell?

    Normally, insulin binds to receptors on the cell surface. This activates the cell's glucose transporter molecules to form a doorway in the cell membrane so that glucose can enter the cell. Therefore, fewer doorways are formed and some glucose is locked out of the cells. Type 2 diabetes is often hard to discover.
