Question: Assume you learned in class that DeltaG for compete oxidation of glucose is -686kcal/mole. Based on the DeltaG for ATP and the numbers of ATP,s produced from complete oxidation of glucose calculate the efficiency of biological oxidation of glucose by respiration. Considering caloric values of carbohydrates, fats and proteins are 4kal/g, 9kal/g and 4kal/g respectively, how many grams of carbs and fat are needed by a marathon runner who uses a total of 2500 kcal(30% calories coming from carbs and 70% calories from fat in the run?
