Chemistry · Proteins: Elementary idea of a-amino acids, peptide bond, polypeptides, proteins: primary, secondary, tertiary and quaternary structure (qualitative idea only), denaturation of proteins, enzymes

During the process of digestion, the protein present in food materials are hydro

During the process of digestion, the protein present in food materials are hydrolysed to amino acids. The two enzymes involved in the process are: Proteins Enzyme \( \quad(A) \) Polypeptides Enzyme\( ^{(B)} \) Amino acids

  • A. Invertase and zymase
  • B. Amylase and maltase
  • C. Diastase and lipase
  • D. Pepsin and trypsin

Step-by-step solution

The diagram shows protein digestion: proteins are broken into polypeptides by Enzyme A, and then polypeptides into amino acids by Enzyme B. Pepsin is a protease that breaks proteins into polypeptides in the stomach, and trypsin is a protease that breaks polypeptides into amino acids in the small intestine. Other options involve enzymes for carbohydrates (amylase, maltase, invertase, zymase) or fats (lipase), not proteins.
