The gastric juice contains proteins splitting enzymes namely

Options

A. pepsin and renin
B. pepsin and trypsin
C. renin and amylase
D. trypsin and chymotrypsinogen

Explanation

**Step-by-Step Solution:**

1. **Understanding Gastric Juice**: Gastric juice is a digestive fluid produced in the stomach, containing various enzymes and acids that help in the digestion of food, particularly proteins.

2. **Identifying Protein-Splitting Enzymes**: The question specifically asks for protein-splitting enzymes present in gastric juice. These enzymes are known as proteases.

3. **Key Enzymes in Gastric Juice**: The two main protein-splitting enzymes found in gastric juice are:
- **Pepsinogen**: This is an inactive form of the enzyme pepsin, secreted by the chief cells in the gastric glands.
- **Prorenin**: Another enzyme that is also present in gastric juice, which is activated to renin.

4. **Activation of Pepsinogen**: Pepsinogen is converted into its active form, pepsin, when it comes into contact with hydrochloric acid (HCl) secreted by the parietal cells in the stomach. Pepsin then breaks down proteins into smaller peptides known as peptones and proteoses.

5. **Role of Renin**: Renin (activated from prorenin) is particularly important in infants as it helps digest milk proteins.

6. **Conclusion**: The correct answer to the question regarding the protein-splitting enzymes present in gastric juice is **pepsin and renin**.

**Final Answer**: The gastric juice contains protein-splitting enzymes namely **pepsin and renin**.
