OA it will be converted to malate to be removed from the mitochondria to be used in gluconeogenesis in the faste state OB. it will be replenished by the action of pyruvate carboxylase in the fed state Ocit will condense to form citrate with acetyl CoA in the tricarboxylic acid cycle in the fed state O D.it will condense to form citrate with acetyl CoA in the tricarboxylic acid cycle in the fasted state OE none of the above statements (A, B, C, or D) are incorrectQuestion 7 Which of the following statements is CORRECT? The activity of the alpha(1,6)glucosidase produces a glucose-1-phosphate product. UDP-glucose pyrophosphorylase activated glucose-1-phosphate by producing UDP-glucose. Oa-Amylase digests glycogen by cleaving alpha(1,6) linkages to produce glucose- 6-phosphate and limit dextrins. Glycogen phosphatase removes the phosphate from glucose-1-phosphate to allow free glucose to be released into the blood. Question 8 Which of the following statements is CORRECT in response to epinephrine? There will be an increase in glycogen synthesis, gluconeogenesis, and amino acid metabolism with an increase in activity in the urea cycle. Protein phosphatase 1 will dephosphorylate acetyl-CoA synthetase resulting in increased production of mevalonate.
