O 4 O 38 36QUESTION 2 ADP AG"=-18.9 kJ/mol 1,3-Bisphosphoglycerate → 3-Phosphoglycerate Normal free energy of the shown step of glycolysis coupled with synthesis of one molecule of ATP is -18.9 kJ/mol. Calculate AG" (in kJ/mol) of dephosphorylation of 1,3-Biphosphoglycerate if AG"¹ of synthesis of ATP from ADP is 1.75. ATP AG" = 1.75 kJ/molQuestion 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. The activation of phosphorylase kinase will activate glycogen synthase and inhibit the activity of glycogen phosphorylase. Protein kinase A activation will phosphorylate glycogen synthase to reduce its…
