Pyruvate generated by glycolysis is converted to acetyl-coenzyme A, which is metabolized by the citric acid cycle generating energy-rich molecules. Select the right combination of these molecules produced from one molecule of acetyl-CoA.

Match the biochemical/metabolic pathways listed in Column I with their correct physiological descriptions during physical exercise listed in Column II: Column I I. Glycolysis II. Beta-oxidation III. Gluconeogenesis IV. Cori cycle Column II 1. Breakdown of fatty acids into acetyl-CoA to yield ATP 2. Synthesis of glucose from non-carbohydrate precursors during fasting/prolonged exercise 3. Anaerobic conversion of glucose to pyruvate 4. Recycling of lactate produced by muscles into glucose in the liver
