Question

Choose the function of the pancreatic juice from the following?

• A. Trypsin digest proteins and lipase carbohydrates.
• B. Trypsin digest 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:

1. Pancreatic juice is a digestive enzyme-rich liquid that is released by the pancreas and contains trypsinogen, chymotrypsinogen, elastase, carboxypeptidase, and pancreatic lipase, nucleases, and amylase.
2. Our pancreas produces pancreatic fluids known as enzymes during digestion.
3. These enzymes result in the breakdown of carbohydrates, lipids, and starches.
4. Trypsin is an enzyme that aids in protein digestion.
5. Trypsin degrades proteins in the small intestine, completing the digesting process that began in the stomach.
6. It is also referred to as a proteolytic enzyme or proteinase.
7. Lipase is an enzyme that the body utilizes to break down lipids in diet and absorb them in the intestines.
8. Fats and oils are triglycerides and fatty acid esters.
9. Hydrolysis can degrade fats and oils, releasing triglycerol and fatty acids.

Explanation of the incorrect options:
Option A:

1. Starches and sugars are broken down mechanically (through chewing) and chemically (via enzymes) into single units of glucose, fructose, and/or galactose, which are absorbed into the bloodstream and transported for use as energy throughout the body.
2. Lipase is an enzyme that the body utilizes to break down lipids in diet and absorb them in the intestines.
3. Fats and oils are triglycerides and fatty acid esters.
4. Hydrolysis can degrade fats and oils, releasing triglycerol and fatty acids.

Option B:

1. Lipase can break down fats into fatty acids and glycerol.
2. These emulsified fats are now broken down into fatty acids and glycerol by pancreatic lipase and intestinal lipase.
3. In addition, trypsin digests proteins in our bodies.

Option C:

Trypsin digests proteins in our bodies.

Final answer: The function of the pancreatic juice from the following was trypsin digests proteins and lipase hydrolyses fats.
