Proteolytic enzymes are not the components of

Options

A. Saliva
B. Gastric juice
C. Succus entericus
D. Pancreatic juice

Answer

To solve the question "Proteolytic enzymes are not the components of," we need to analyze the options provided and understand where proteolytic enzymes are typically found.

### Step-by-Step Solution:

1. **Understand Proteolytic Enzymes**:
- Proteolytic enzymes, also known as proteases, are enzymes that break down proteins into smaller peptides or amino acids. They are crucial for protein digestion.

2. **Identify the Options**:
- The options given are:
- A) Saliva
- B) Gastric juice
- C) Succus entericus
- D) Pancreatic juice

3. **Analyze Each Option**:
- **A) Saliva**: Saliva primarily contains enzymes like amylase (which breaks down carbohydrates) but does not contain significant amounts of proteolytic enzymes.
- **B) Gastric Juice**: Gastric juice contains pepsin, a well-known proteolytic enzyme that helps in protein digestion.
- **C) Succus Entericus**: This is the intestinal juice secreted by the intestinal glands, which contains several enzymes, including proteases like trypsin and chymotrypsin.
- **D) Pancreatic Juice**: This juice contains several proteolytic enzymes, including trypsin, chymotrypsin, and carboxypeptidase, which are essential for protein digestion.

4. **Conclusion**:
- Based on the analysis, the only option that does not contain proteolytic enzymes is **A) Saliva**. Therefore, the answer is that proteolytic enzymes are not components of saliva.

### Final Answer:
Proteolytic enzymes are not the components of **saliva**.
