Intracellular stores of glucose are very low and the cells feel starved b. All of the above explain why this happens c. Most of the glucose leaves through the kidneys since glucose has exceeded Tmax d. Circulating fat stores are low, which promotes lipolysis e. A lack of insulin results in chronic sympathetic drive, using up all the blood glucose
