Question

Choose the function of the pancreatic juice from the following :-

• A. Trypsin digests proteins and lipase carbohydrates.
• B. Trypsin digests emulsified fats and lipase proteins.
• C. Trypsin and lipase digest fats.
• D. Trypsin digests proteins and lipase hydrolyses fats.

Answer 1

The correct option is D

Trypsin digests proteins and lipase hydrolyses fats.

The correct option is D.

Explanation of the correct option:

Option D:

1. Trypsin is produced by the pancreas in the inactive form of trypsinogen.
2. It is a protease that helps in digesting proteins.
3. It breaks down proteins in the small intestine.
4. Lipase hydrolyses triglycerides (fats) into their components fatty acid and glycerol molecules.

Explanations for the incorrect options:
Option A:

1. An enzyme that helps in digestion is called trypsin.
2. A protein that accelerates a certain biological reaction is called an enzyme.
3. The small intestine is where trypsin is located.
4. We can digest protein with the aid of the enzyme trypsin.
5. Trypsin breaks down proteins in the small intestine, carrying on the digestive process that started in the stomach.
6. The body employs the enzyme lipase to digest dietary fats so they may be absorbed in the intestines.
7. The pancreas, mouth, and stomach all manufacture lipase.

Option B:

1. Lipase can then work to break down the fats into fatty acids and glycerol.
2. Pancreatic lipase and intestinal lipase are now responsible for dissolving these emulsified lipids into fatty acids and glycerol.
3. We can digest protein with the aid of the enzyme trypsin.

Option C:

1. We can digest protein with the aid of the enzyme trypsin.
2. In order to enzymatically digest lipid molecules, the digestive process first breaks those large droplets of fat into smaller droplets using lipases.

Final Answer: The function of pancreatic juice is that trypsin digests proteins and lipase hydrolyses fats.
