The catabolism of glycogen in the muscle results in the production of glucose-6-phosphate whereas catabolism in the liver results in the formation of glucose. Which statement below best explains the reasoning beehind this difference in catabolism? a) The liver typically has a higher energy charge than the muscle. Removal of the phosphate allows the liver to form more ATP accounting for this higher energy charge. b) The glucose-6-phosphate phosphatase (which catalyzes the removal of the phosphate) in the muscle has a higher Km than the isozyme found in the liver. c) Glycogen found in the muscle is a polymer of glucose-6-phosphate whereas in the liver the polymer is produced from free glucose. d) The liver stores and catabolizes glycogen in order to maintain blood sugar levels. Removal of the phosphate to form glucose allows the molecule to readily pass through the membrane into the bloodstream. QUESTION 2 Which of the following is not a noncarbohydrate precursor which can form glucose via the gluconeogenesis pathway? a) Acetyl CoA b) Oxaloacetate c) Pyruvate d) Glycerol
