試題詳解

 1. The conversion of 1 mole of frctose 1,6-bisphosphate to 2 mole of pyruvate by the glycolytic 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-phosphoglycerate involves oxidation of NADH to NAD+. 

 3.Acetate cannot serve as the starting material for the synthesis of glucose via gluconeogenesis 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 the production of 3 mole of pentose, 4 mole of NADPH, and 3 mole of CO₂.
