Question

Which one is not the use of hepatic portal system?

• A. To convert carbohydrate into glycogen.
• B. To separate ammonia.
• C. To kill bacteria.
• D. To convert protein into carbohydrate.

Answer 1

Answer: (D)

To convert protein into carbohydrate.

The hepatic portal system is the system of blood vessels that connect the gastrointestinal system and the liver. The nutrients digested by the intestines are transported to the liver, where the excess of carbohydrates is converted into glycogen. The amino acids are broken down and ammonia is released, which is soon converted to urea through the Ornithine cycle. The liver has Kupffer cells that kill the bacteria before the nutrients move out to the different organs of the body.

Hence, the correct answer is 'To convert proteins into carbohydrates'
