Explanation:

The gall bladder is a small organ located beneath the liver. Its main role is to store and concentrate bile, which is produced by the liver.


What is bile and what does it do?

- Bile is a greenish fluid that contains bile salts.
- It plays a crucial role in the emulsification of fats, breaking large fat globules into smaller ones to make them easier for lipase enzymes to digest.


What happens if the gall bladder is removed?

- The liver still produces bile, but it can no longer be stored and concentrated in the gall bladder.
- Instead, bile drips directly into the small intestine.
- This slows down fat digestion, especially after a high-fat meal, because bile is not available in large amounts when suddenly needed.


Let's consider the other options:

- B. Formation of urea – This occurs in the liver, not related to the gall bladder.
- C. Digestion of starch – Handled by amylase in the mouth and small intestine, not related to bile.
- D. Conversion of protein – Proteins are digested mainly by pepsin and trypsin, not affected by bile.
- E. Storage and release of urine – Done by the urinary bladder, not the gall bladder.

The gall bladder assists in fat digestion by storing and releasing bile. Removing it most affects the digestion of fats and oils.

Correct Answer: A. Digestion of fats and oil
