Which of the following is not a function of the mammalian liver?

• A. Detoxification of the blood
• B. Regulation of blood glucose levels
• C. Preparation of nitrogenous wastes for disposal through urine
• D. Production of the enzyme pepsinogen

Answer 1

The correct option is D

Production of the enzyme pepsinogen

The correct option is (C)

Explanation of correct option:

1. The liver is the largest organ in the human body, brown in colour and produces bile which is used for the breakdown of fats in the small intestine.
2. The liver does not produce the enzyme pepsinogen, it is produced by the gastric glands within the stomach.

Explanation of incorrect option:

Option (A):

1. The liver is known to purify the blood and extract all the toxins by the help of some immune cells that extract the toxin, digest it and finally eliminate it out of the system.

Option (B):

1. The liver can store glucose in the form of glycogen.
2. When there is a need for glucose within the blood the glycogen is broken down to replenish the blood glucose levels.

Option (C):

1. The urea that is excreted via the urine gets formed within the liver.
2. The liver secretes enzymes that convert the ammonia synthesized by leftover amino acids and convert them to urea which gets concentrated by the kidneys and then released via urine.

Final answer:

Production of the enzyme pepsinogen is not a function of the liver.
