Perpsin:1. It is secreted from the gastric glands of stomach.2. It is secreted in inactive form called pepsinogen.3. It acts on protein and converts them into proteoses and peptones.4. It catalyses in acidic medium.Trypsin:1. It is secreted from the exocrine pancreas.2. It is secreted in inactive form called trypsinogen.3. It acts on proteoses and peptones and converts them into polypeptides.4. It catalyses in alkaline medium.
Pepsin produce in stomach on the other hand trypsin produce by pancreas
Pepsin is acidic in nature on the other hand trypsin is alkaline in nature
Pepsin works in acidic medium but tripsin works in basic medium
Pepsin is gastric enzyme but tripsin is succusentericus
