When we have not eaten for a while,
blood
glucose levels fall, which prompts a
decrease in insulin and an
increase in
glucagon.
Low blood glucose triggers the alpha cells of
pancreas to release glucagon. It prompts the liver to release glucose it has
stored in its cells into the bloodstream. This increases the glucose in the
blood. Insulin responds to blood sugar level opposite to glucagon. Insulin
increases with high blood sugar.
