Main function of enterokinase is :

Options

A. Conversion of casein into paracasein
B. Concersion of pepsinogen
C. Conversion of trypsinogen into trypsin
D. Conversion of trypsin into trypsinogen

Answer

**Step-by-Step Solution:**

1. **Understanding Enterokinase**: Enterokinase is an enzyme that is produced in the intestinal mucosa. It plays a crucial role in the digestive process.

2. **Function of Enterokinase**: The main function of enterokinase is to activate trypsinogen, which is an inactive form of the enzyme trypsin.

3. **Activation Process**: Enterokinase converts trypsinogen into trypsin. Trypsin is a protein-digesting enzyme that is essential for the digestion of proteins in the food we consume.

4. **Further Activation**: Once trypsin is activated, it can further activate other enzymes present in pancreatic juice, such as chymotrypsinogen (to chymotrypsin) and procarboxypeptidase (to carboxypeptidase), which also aid in protein digestion.

5. **Conclusion**: Therefore, the main function of enterokinase is to convert trypsinogen into trypsin.

6. **Identifying the Correct Option**: Among the options provided, the correct answer is the conversion of trypsinogen to trypsin (Option C).
