In certain cells pyruvate can be reconverted to glucose during gluconeogenesis. How many ATPsare required to convert pyruvate back to glucose?Glucose-6-phosphate is an important intermediate in glycolysis pathway. Briefly explain how this intemediate could be generated from glycogen and dietary starch.

Presumably, fat could be oxidized without concomi- tant ATP synthesis for re-formation of fat or carbohydrate. Why was this a bad (i.e., fatal) idea?Glycerol backbone of a fat molecule can be converted to glyceraldehyde-3-phosphate, an intermediate in glycolysis. Assuming that the single glyceraldehyde-3-phosphate undergoes complete oxidation to CO₂, how many ATPs are produced by oxidative phosphorylation only (i.e. exclude ATPs from substrate level phosphorylation) from a single fat molecule?
