Which of following are true concerning ketone bodies? Ketone bodies are made from the acetyl-CoA molecules coming off of the PDC. The brain will convert ketone bodies back into acetyl-CoA to sustain the TCA cycle and yield ATP molecules from ETC + ATP Synthase Ketone bodies are made from acetyl-CoA that is generated from beta-oxidation A low carbohydrate, high fat, moderate/low protein diet will cause the production of ketone bodies. Ketone bodies are produced in healthy individuals when blood glucose is high. Acetone, acetoacetate and beta-hydroxybutyrate are considered ketone bodies. Ketone bodies are made by glycolysis. Ketone bodies are produced in persons with untreated diabetes.

All of the following statements about ketone bodies are true except for which one? They are an important fuel in the fasted state They are produced in liver mitochondria They are synthesized from HMG-CoA (hydroxymethylglutaryl-CoA) They can be converted to glucose in the fasting kidney. They can be made from the products of both fatty acid and amino acid breakdown.
