During the fasting state, the energy stores of the liver become the major source of glucose for the whole body. The liver releases glucose into the bloodstream through glycogenolysis, breaking down glycogen reserves. Additionally, gluconeogenesis occurs, where the liver synthesizes glucose from non-carbohydrate sources like amino acids and glycerol. This process helps maintain blood glucose levels for essential functions, particularly in the brain and muscles.
