Question

Pepsin digests

• A. Proteins in stomach
• B. Carbohydrates in duodenum
• C. Proteins in duodenum
• D. Fats in ileum

Answer 1

The correct option is A Proteins in stomach

Pepsin is an enzyme whose zymogen (pepsinogen) is released by the chief cells in the stomach and that degrades food proteins into peptides.

During the process of digestion, these enzymes, each of which is specialized in severing links between particular types of amino acids, collaborate to break down dietary proteins into their components, i.e., peptides and amino acids, which can be readily absorbed by the intestinal lining. Pepsin is most efficient in cleaving peptide bonds between hydrophobic and preferably aromatic amino acids such as phenylalanine, tryptophan, and tyrosine

So, the correct answer is 'Proteins in stomach'
