One possible sign of insulin deficlency is "acetone breath" in which ketone bodies accumulate in the blood. These ke bodies arise from what aspect of metabolism? increased liver temperature that denatures enzymes of the glycolysis pathway lack of glucose input into the glycolysis pathway excess fatty acid input into the beta-oxidation pathway due to high levels of triglycerides in adipocytes excess glucose input into the glycolysis pathway loss of mitochondrial cytochrome c activity and subsequent electron transport
