Question

Which of the following is not the function of the liver?
(A) Conversion of glucose to glycogen
(B) Conversion of glycogen to glucose
(C) Detoxification of poisonous substances
(D) Breakdown of cholesterol

Answer 1

Hint: Liver is the vital organ that performs many functions in the body. It is located in the upper side of the right corner of the abdomen that is below the diaphragm. It looks reddish brown with the two lobes of the right and the left lobes.

Complete Answer:
- Liver does many functions in daily growth and metabolism like the production, storage and the production of the various substances. It helps in the secreting of the bile juice which is used in the digestion in the gallbladder.

- It also plays the role in the detoxification of the poisonous ammonia that is produced in the blood.
- The liver performs examination of the ammonia and thus it gets converted into the urea. Which in turn released in the urine. Hence the first chemical process of the excretion takes place in the liver.
- The excess glucose gets converted into glycogen and stores in them. When there is no glucose in the body, the glycogen stored in them is converted into glucose and used by the cells.
- These are performed by the insulin and the glucagon hormones of the pancreas. The liver also helps in the destruction of the old red blood cells in the adults. So the breakdown of the cholesterol is not the role of the liver.

Thus the option (D) is correct.

Note: The breakdown of the fats in the cholesterol is done by the lipase enzymes that are produced in the cells. This process is called the fat acid catabolism which releases several ketone bodies in the blood and there in urine. These fats are used in the release of energy.
