The pancreatic juice contains various enzymes, except

Options

A. Pepsinogen
B. Trypsinogen
C. Chymotrypsinogen
D. Procarboxypeptidases

Answer

### Step-by-Step Text Solution:

1. **Understanding Pancreatic Juice**:
- Pancreatic juice is a digestive fluid secreted by the pancreas. It plays a crucial role in the digestion of food in the small intestine.

2. **Components of Pancreatic Juice**:
- The pancreatic juice contains several important enzymes that aid in digestion:
- **Trypsinogen**: An inactive precursor (zymogen) that is activated to trypsin, which helps in protein digestion.
- **Chymotrypsinogen**: Another zymogen that is activated to chymotrypsin, also involved in protein digestion.
- **Procarboxypeptidase**: A zymogen that is converted to carboxypeptidase, which further aids in protein digestion.
- **Pancreatic Amylase**: Enzyme that breaks down carbohydrates (starch).
- **Pancreatic Lipase**: Enzyme that breaks down fats (lipids).
- **Nucleases**: Enzymes that digest nucleic acids.

3. **Identifying the Exception**:
- Among the options provided, we need to determine which enzyme is NOT present in pancreatic juice.
- The options are:
- A) Pepsinogen
- B) Trypsinogen
- C) Chymotrypsinogen
- D) Procarboxypeptidase

4. **Analyzing Each Option**:
- **Pepsinogen**: This enzyme is not found in pancreatic juice; it is secreted by the gastric glands in the stomach and is part of gastric juice.
- **Trypsinogen, Chymotrypsinogen, and Procarboxypeptidase**: All of these are present in pancreatic juice as zymogens.

5. **Conclusion**:
- The correct answer is **A) Pepsinogen**, as it is the only enzyme listed that is not part of pancreatic juice.
