Regulation of metabolism and body temperature ch 24. Insulin activity deficient or absent; insulin has no back-up hormone: blood glucose is high after a meal but cells are unable to utilize glucose for energy production.

If this becomes too severe it can disrupt processes including cns, heart activity and o2 transport, leading to coma and death: acetone in breath is a sign of ketosis ketone body that can be produced from acetyl-coa. Metabolic role of liver conducts over 500 metabolic fns (one of most biochemically complex organs in the body) processes nearly every class of nutrients and plays a major role in regulations of plasma cholesterol levels.
