Why Is Insulin A Negative Feedback? | DiabetesTalk.Net Read about our approach to external linking. Exercise can therefore be a useful way to reduce blood glucose levels and can be particularly useful in people with type 2 diabetes Following exercise, the muscles will try to replenish their stores of glycogen and will therefore take in available glucose from the blood to do so, helping to lower blood glucose over this period. The control of blood sugar (glucose) by insulin is a good example of a negative feedback mechanism. hexokinase, PFK-1 and pyruvate DH. In glycogenolysis, glucagon instructs the liver to convert glycogen to glucose, making glucose more available in the bloodstream. It is also used as a medication to treat a number of health conditions. People with Type 1 diabetes primarily use this form of glucagon in emergency situations when they have very low blood sugar.
