Trypsin differs from pepsin in that it digest :-

Options

A. Protein in alkaline medium in stomach
B. Protein in acid medium in duodenum
C. Protein in alkaline medium in duodenum
D. Protein in acidic medium in stomach

Answer

### Step-by-Step Solution:

1. **Understanding the Enzymes**:
- Trypsin and pepsin are both digestive enzymes that break down proteins, but they function in different environments and have different roles in digestion.

2. **Location of Action**:
- Pepsin operates in the stomach, where the environment is acidic due to the presence of hydrochloric acid. This acidic medium is essential for pepsin's activity.
- Trypsin, on the other hand, functions in the small intestine, specifically in the duodenum, where the environment is alkaline (basic).

3. **Nature of the Medium**:
- Pepsin digests proteins in an acidic medium, breaking down proteins into smaller peptides.
- Trypsin digests proteins in an alkaline medium, further breaking down these peptides into smaller polypeptides and eventually into amino acids.

4. **Function of the Enzymes**:
- Pepsin begins the digestion of proteins in the stomach by breaking them down into smaller chains called polypeptides.
- Trypsin continues this process in the small intestine, converting these polypeptides into even smaller peptides and amino acids, which can then be absorbed by the body.

5. **Conclusion**:
- Therefore, the key difference is that trypsin digests proteins in an alkaline medium in the duodenum, while pepsin digests proteins in an acidic medium in the stomach.

### Final Answer:
Trypsin differs from pepsin in that it digests proteins in an alkaline medium in the duodenum.
