Question

Chymotrypsin helps in the breakdown of

• A. proteins
• B. peptones
• C. proteoses
• D. all the above

Answer 1

The correct option is D all the above

Trypsin, chymotrypsin and carboxypeptidase are proteases, which break down proteins into smaller peptides. Proteins, proteoses and peptones (partially hydrolysed proteins) in the chyme (semi-fluid mass of partially digested food) reaching the intestine are acted upon by the proteolytic enzymes of the pancreatic juice such as trypsin, chymotrypsin and carboxypeptidase:

$\begin{array}{c}\text{Proteins}\\ \text{Peptones}\\ \text{Proteoses}\end{array}\}\underset{\text{Carboxypeptidase}}{\overset{\text{Trypsin/Chymotrypsin}}{\to }}\text{Dipeptides}$
