Assertion (A): All the proteins in our food are digested in small intestine only. Reason (R): The protein-digesting enzyme from pancreas are released into small intestine.
✓ Correct answer: d) A is false but R is true
ExplanationThe process of conversion of complex food substances to simple absorbable forms is called digestion and is carried out by our digestive system by mechanical and biochemical methods.Assertion A is False: Protein digestion is not limited to the small intestine alone.Protein digestion begins in the stomach, where the enzyme pepsin breaks down proteins into smaller peptides.The process continues in the small intestine, where pancreatic enzymes (like trypsin and chymotrypsin) and intestinal enzymes (like peptidases) further break down peptides into amino acids.Reason R is True: The pancreas secretes several protein- digesting enzymes such as trypsin, chymotrypsin, and carboxypeptidase into the small intestine.These enzymes play a crucial role in breaking down proteins into smaller peptides and amino acids.440
