Vedclass · Answer

(D) During prolonged fasting,the body lacks a sufficient supply of carbohydrates for energy. To meet its energy requirements,the body begins to break down stored fats through a process called lipolysis. This leads to the production of fatty acids,which are then converted into ketone bodies (such as acetoacetate,beta-hydroxybutyrate,and acetone) in the liver. When the concentration of these ketone bodies in the blood exceeds the renal threshold,they are excreted in the urine,a condition known as ketonuria.
