Question

Which of the following are the correct functions of two components of pancreatic juice trypsin and lipase?

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

Answer 1

The correct option is D Trypsin digests proteins and lipase emulsified fats.

Pancreatic juice contains trypsinogen, which is inactive zymogen form of trypsin which is activated by enteropeptidase (also called as enterokinase) and acts on proteins.
Fats need to be emulsified before digestive enzymes can act on them because fats are not soluble in water. Fats or lipids are acted on by lipases.
