Zoology - Digestion and Absorption Question with Solution | TestHub
In the following flowchart about protein digestion, P, Q, R and S are enzymes.
The correct information of enzymes P, Q, R and S is
Options:
Answer:
Solution:
P- pepsin produced by stomach as pepsinogen. It is activated at acidic pH. It converts proteins into proteoses and peptones. Q- Trypsin or chymotrypsin produced by pancreas as trypsinogen or chymotrypsinogen. Trypsin is activated by enterokinase from the intestine. It can convert peptones and proteoses to polypetides. R- Aminopeptidase produced intestine in an active form. R could also be carboxypeptidase produced by pancreas as procarboxypeptidase. Both of them can convert polypetides to dipeptides. In this contect it is aminopeptidase. S is dipeptidase produced by intestine in an active form. It converts dipeptides to amino acids
