The correct answer is:
P: Produced by stomach as a proenzyme and is activated at acidic pH
Q: Produced by pancreas as a proenzyme and is activated by an intestinal enzyme
R: Produced by intestine in an active state
S: Produced by intestine in an active state
Q: Produced by pancreas as a proenzyme and is activated by an intestinal enzyme
R: Produced by intestine in an active state
S: Produced by intestine in an active state
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
