BLOOD SUGAR REGULATION Cells receive most of their carbohydrate as glucose Homeostasis - the tendency of living organisms to maintain a constant  environment, such as a constant temperature, pH, and concentrations of solutes  When blood glucose levels begin to fall below normal, the liver breaks down  stored glycogen into glucose and releases this into the bloodstream  When we have used up our carbohydrate stores, the body uses  gluconeogenesis  to synthesize glucose from certain amino acids  Hormones are the triggers for release of glycogen and gluconeogenesis Glucagon - hormone which raises blood sugar by triggering glycogen breakdown
