34. Which of the following four statements regarding glycolysis and gluconeogenesis is correct?  1. The conversion of 1 mole of frctose 1,6-bisphosphate to 2 mole of pyruvate by theglycolytic pathway results in a net formation of 2 mole of NAD+ and 4 mole of ATP.  2. The step of glycolysis between glyceraldehyde 3-phosphate and 3-phosphoglycerateinvolves oxidation of NADH to NAD+.  3.Acetate cannot serve as the starting material for the synthesis of glucose viagluconeogenesis in animals.  4. Pyruvate kinase is used in both glycolysis and gluconeogenesis.  5.The oxidation of 3 mole of glucose by the pentose phosphate pathway may result in theproduction of 3 mole of pentose, 4 mole of NADPH, and 3 mole of CO2.
