✔ 最佳答案
D.Urea is the breakdown of protein and it happens in the liver not in the intestine.
Insulin is secreted due to high glucose concentration in the blood to reduce glucose level by converting glucose to glycogen. 12 hours without any ingestion of food, means low glucose concentration in the blood.
Glucose will increase after digestion and absorption of the food.
