Trypsin differs from pepsin in that:
1. Trypsin digests protein in an alkaline medium while pepsin does so in an acidic medium
2. Trypsin is secreted from the gastric glands while pepsin is secreted from the pancreas
3. Trypsin digests protein in an acidic medium while pepsin does so in an alkaline medium
4. Trypsin digests fat and pepsin digests protein
1. Trypsin digests protein in an alkaline medium while pepsin does so in an acidic medium
2. Trypsin is secreted from the gastric glands while pepsin is secreted from the pancreas
3. Trypsin digests protein in an acidic medium while pepsin does so in an alkaline medium
