Question

Trypsin a digestive enzyme occurs in which part of GI tract, acts on and works in which condition

• A. Starch in buccal cavity in an alkaline medium
• B. Protein in stomach in an acidic medium
• C. Protein in duodenum in an acidic medium
• D. Protein in duodenum in an alkaline medium

Answer 1

The correct option is D Protein in duodenum in an alkaline medium

• Trypsin is a serine protease found in the digestive system of many vertebrates, where it hydrolyzes proteins.
• Trypsin is the active form of trypsinogen, secreted by the pancreas into the duodenum, which is activated by enterokinase secreted by the cells of the small intestine.
• In the duodenum, trypsin catalyzes the hydrolysis of peptide bonds, breaking down proteins into smaller peptides which occurs in the small intestine where a slightly alkaline environment (about pH 8). Hence, Trypsin a digestive enzyme secreted by the pancreas and works in the alkaline medium.

So, the correct answer is 'Protein in the duodenum in an alkaline medium'.
