The enzyme in which alternative is matched with its respective function ?

Options

A. `{:("Enzyme","Function"),("Lysozyme","Activates trypsinogen"):}`
B. `{:("Enzyme","Function"),("Pepsin","Antibacterial agent"):}`
C. `{:("Enzyme","Function"),("Rennin","Digestion of milk protein"):}`
D. `{:("Enzyme","Function"),("Enterokinase","Absorption of water"):}`

Answer

To solve the question regarding which enzyme is correctly matched with its respective function, we will analyze each enzyme and its proposed function step-by-step.

### Step-by-Step Solution:

1. **Identify the Enzymes and Their Functions**:
We have four enzymes with their respective functions to evaluate:
- **Lysozyme**: Proposed function - activates trypsinogen.
- **Pepsin**: Proposed function - antibacterial agent.
- **Renin**: Proposed function - digestion of milk protein.
- **Enterokinase**: Proposed function - absorption of water.

2. **Evaluate the First Option (Lysozyme)**:
- **Lysozyme** is known to be present in saliva and acts as an antibacterial agent. It does not activate trypsinogen.
- **Conclusion**: This match is incorrect.

3. **Evaluate the Second Option (Pepsin)**:
- **Pepsin** is a proteolytic enzyme that digests proteins in the stomach. It is not an antibacterial agent; that role belongs to lysozyme.
- **Conclusion**: This match is incorrect.

4. **Evaluate the Third Option (Renin)**:
- **Renin** is indeed a proteolytic enzyme that is involved in the digestion of milk proteins, particularly in infants. It helps coagulate milk, making it easier to digest.
- **Conclusion**: This match is correct.

5. **Evaluate the Fourth Option (Enterokinase)**:
- **Enterokinase** is an enzyme that activates trypsinogen to trypsin and is not involved in the absorption of water.
- **Conclusion**: This match is incorrect.

6. **Final Conclusion**:
After evaluating all the options, the only correct match is:
- **Renin**: Digestion of milk protein.

### Answer:
The correct enzyme matched with its respective function is **Renin - Digestion of milk protein**.
