- Adults engaged in strenuous physical activity require an intake of about 160 g of carbohydrate daily but only about 20 mg of niacin for optimal nutrition. Given the role of niacin in glycolysis, how do you explain the observation?In healthy adults, the concentration of glucose in blood is approximately80 to 110 milligrams per deciliter (mg/dl). After a carbohydrate-richmeal, however, the concentration may spike to 140 mg/dl. Describe thehormonal action that returns blood glucose to normal.Name the molecules used for gluconeogenesis. What are the sources of these molecules? Under what conditions would gluconeogenesis occur?
