A second hallmark of glycogen-synthase deficiency is high levels of ketone bodies. Which of the following explains this symptom? A) When tissues are starved of glucose, the liver responds by making ketone bodies B) Beta oxidation is intact in these patients. Therefore, the liver of these patients can still readily create the substrate of ketone-body synthesis, acetyl-CoA, despite low levels of pyruvate. C) Since glucogenic intermediates, like pyruvate, are needed for anaplerosis, Krebs intermediates are low. This leads to a...

Describe how glucose is instrumental in the formation of FA. How does glucose provide the energy and raw materials needed to make palmitate? How many mol ATP, NADPH, and acetyl-CoA needed to make palmitate? How many mol glucose are required for ATP, NADPH, and acetyl-CoA sufficient to make one mol palmitate? What role does citrate lyase and malic enzyme play in palmitate formation?
