Question

The function of enzyme trypsin is to
(a)Breakdown fats
(b)Breakdown proteins
(c)Synthesize proteins
(d)Breakdown carbohydrates

Answer 1

Hint : A large macromolecule consisting of chains of amino acids that provide structure to the cell and is the main substance that constitutes the body.

Complete answer :
Trypsin is a serine protease enzyme that is found in the digestive system of many vertebrates and it hydrolyzes the proteins. It is essential for the digestion of proteins for building and repairing the damaged tissues.

Additional information
-The Pancreas secretes an inactivated enzyme or proenzyme called trypsinogen.
-The activated form of trypsinogen is trypsin which is formed in the stomach and small intestine.
-Trypsin is a protease which breaks the peptide chains at the carboxyl side of the amino acids lysine or arginine.
-In the duodenum, the hydrolysis of peptide bonds occurs through trypsin which breaks the protein molecules into smaller peptides.
-The peptide products are then again hydrolyzed by other protease enzymes and form amino acids.
-These amino acids later become available for absorption into the bloodstream.
-The hydrolysis is important to break large protein molecules so that they can be easily absorbed by the lining of the small intestine.
-Trypsin is being used widely in various biotechnological processes as it is present in higher quantity in the pancreas.

So, the correct answer is ‘Breakdown proteins’.

Note: Trypsin was discovered by Wilhelm Kuhne in 1876 and was named from the ancient Greek word meaning ‘for rubbing’ as it was first isolated by rubbing the pancreas with glycerine. Proteins were first discovered by Dutch chemist Gerardus Johannes Mulder and were named by Swedish chemist Jons Jacob Berzelius in 1838.
