Select the odd with respect to enzymes present in adult human.

Options

A. Carboxypeptidase
B. Rennin
C. Trypsin
D. Pepsin

Answer

To solve the question of selecting the odd one with respect to enzymes present in adult humans, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Enzymes Listed**:
- The question provides a list of enzymes. We need to identify each one and their presence in adult humans. The enzymes mentioned are:
- Carboxypeptidase
- Renin
- Trypsin
- Pepsin

2. **Analyze Each Enzyme**:
- **Carboxypeptidase**:
- This enzyme is produced by the pancreas and is involved in protein digestion. It is secreted in an inactive form (procarboxypeptidase) and activated in the digestive tract. It is present in adult humans.
- **Renin**:
- Renin is an enzyme that is primarily involved in the digestion of milk proteins in infants. It is not present in adult humans, making it unique among the listed enzymes.
- **Trypsin**:
- Trypsin is another enzyme produced by the pancreas. It plays a crucial role in protein digestion and is present in adult humans.
- **Pepsin**:
- Pepsin is secreted by the gastric glands and is involved in protein digestion in the stomach. It is also present in adult humans.

3. **Determine the Odd One Out**:
- After analyzing the presence of each enzyme, we find that:
- Carboxypeptidase, Trypsin, and Pepsin are all present in adult humans.
- Renin is the only enzyme that is absent in adult humans.

4. **Conclusion**:
- Therefore, the odd one out with respect to enzymes present in adult humans is **Renin**.

### Final Answer:
The odd one with respect to enzymes present in adult humans is **Renin**.
