Question

How does feedback mechanisms maintain blood glucose concentration in organisms?

Answer 1

After a meal, you have high blood glucose. Insulin is released and the tissues, mainly the liver takes up the excess glucose. When blood glucose reaches an acceptable level, insulin is no longer released. Once you begin to exercise and use up all the carbohydrate stores in your muscles you blood glucose drops. Glucagon is released which causes glycogen breakdown (into glucose) in the liver. The glucose is released back into the blood to stabilize blood glucose.

This whole thing is controlled by the back and forth action of insulin and glucagon.
