Part A For the following gluconeogenesis reactions, select all of the coupled reactions. NOTE: Pi stands for phosphate. o phosphoenolpyruvate + H20 = 2-phosphoglycerate 0 3-phosphoglycerate + ATP = 1,3-bisphosphoglycerate + ADP o pyruvate + HCO3 + ATP = oxaloacetate + ADP + Pi o fructose-6-phosphate = glucose-6-phosphate

Add coefficients to the reaction summary to show the net results of glycolysis. glucose+? ADP+? Pi+? NAD+⟶? pyruvate+? ATP+? NADHglucose+a ADP+b Pi+c NAD+⟶x pyruvate+y ATP+z NADH You do not need to add the water and hydrogen ions necessary to balance the overall reaction. Then, Draw the structure of pyruvate at pH 7.4.
