Which of the following is found in succus entericus ?

Options

A. Enterokinase and nucleosidase
B. Trypsinogen and lactase
C. Nucleosidase and amylopsin
D. Carboxypeptidase and amylase

Answer

To solve the question "Which of the following is found in succus entericus?", we need to analyze the components typically present in succus entericus (intestinal juice).

### Step-by-Step Solution:

1. **Understanding Succus Entericus**:
- Succus entericus, also known as intestinal juice, is secreted by the intestinal mucosa. It contains various enzymes that aid in digestion.

2. **Identifying the Components**:
- The enzymes found in succus entericus include:
- Dipeptidases
- Lipases
- Nucleosidases
- Disaccharidases (like maltase)
- Enterokinase (which activates trypsinogen to trypsin)

3. **Analyzing the Options**:
- **Option 1**: Anterokinase and Nucleosidase - Both are found in succus entericus.
- **Option 2**: Trypsinogen and Lactase - Trypsinogen is not found in succus entericus; it is produced by the pancreas.
- **Option 3**: Nucleosidase and Amylopsin - Amylopsin is also produced by the pancreas, not found in succus entericus.
- **Option 4**: Carboxypeptidase and Amylase - Carboxypeptidase is produced by the pancreas, and amylase is also not a component of succus entericus.

4. **Conclusion**:
- The only option that contains enzymes found in succus entericus is **Option 1: Anterokinase and Nucleosidase**.

### Final Answer:
The correct answer is **Anterokinase and Nucleosidase**.
