Enzyme enterokinase activates

Options

A. Nucleases
B. Pepsiongen
C. Renim
D. trypisnogen

Answer

To answer the question "Enzyme enterokinase activates", we need to follow these steps:

### Step-by-Step Solution:

1. **Understanding Enterokinase**: Enterokinase is an enzyme produced in the intestinal mucosa. Its primary role is to activate other enzymes that are secreted in an inactive form.

2. **Identifying the Inactive Enzyme**: Among the options provided (A-Nucleases, B-Trypsinogen, C-Renin, D-Trypsinogen), we need to identify which of these is an inactive precursor that enterokinase can activate.

3. **Function of Enterokinase**: Enterokinase specifically activates trypsinogen, which is an inactive form of the enzyme trypsin. When enterokinase acts on trypsinogen, it converts it into its active form, trypsin.

4. **Role of Trypsin**: Once activated, trypsin can further activate other digestive enzymes, such as chymotrypsinogen and procarboxypeptidase, which are also important in protein digestion.

5. **Conclusion**: Since enterokinase activates trypsinogen, the correct answer to the question is **D-Trypsinogen**.

### Final Answer:
The enzyme enterokinase activates **D-Trypsinogen**.
