Trypsin differs from pepsin because it digests :

Options

A. Carbohydrate in alkaline medium in stomach
B. Protein, in alkaine medium in stomach
C. Protein, in acidic medium of stomach
D. Protin, in alkaine madium in duodenum

Answer

To answer the question, "Trypsin differs from pepsin because it digests:", we need to analyze the differences between these two enzymes in terms of their function and the conditions under which they operate.

### Step-by-Step Solution:

1. **Identify the Enzymes**:
- Trypsin and pepsin are both digestive enzymes that play crucial roles in protein digestion.

2. **Understand the Source**:
- Pepsin is produced in the stomach and is active in the acidic environment of the stomach (pH around 1.5 to 3.5).
- Trypsin is produced in the pancreas and is active in the small intestine, specifically in the duodenum, where the pH is alkaline (around 7 to 8).

3. **Function of Pepsin**:
- Pepsin primarily digests proteins into smaller peptides in the acidic medium of the stomach.

4. **Function of Trypsin**:
- Trypsin continues the process of protein digestion by breaking down peptides into even smaller units (dipeptides) in the alkaline medium of the duodenum.

5. **Analyze the Options**:
- **Carbohydrate in alkaline medium in stomach**: Incorrect. Trypsin and pepsin do not digest carbohydrates.
- **Protein in alkaline medium in stomach**: Incorrect. Trypsin does not act in the stomach; it acts in the small intestine.
- **Protein in acetic medium in stomach**: Incorrect. Trypsin does not act in an acetic medium.
- **Protein in alkaline medium in duodenum**: Correct. This accurately describes the action of trypsin.

6. **Conclusion**:
- Therefore, the correct answer is that trypsin differs from pepsin because it digests protein in alkaline medium in the duodenum.

### Final Answer:
Trypsin differs from pepsin because it digests protein in alkaline medium in the duodenum.
