A : Trypsin is an example of endopeptidase and is present in the pancreatic juice.
R : Trypsin acts on the interior peptide of a protein molecule.

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion
B. If both Assertion is true but the reason is not the correct explanation of the assertion,
C. If Assertion is true statement but Reason is false
D. If both Assertion and Reason are false statements

Answer

To analyze the statements given in the question, we will break down the assertion (A) and the reason (R) step by step.

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states that "Trypsin is an example of endopeptidase and is present in the pancreatic juice."
- **Explanation**: Trypsin is indeed classified as an endopeptidase, which means it is an enzyme that breaks down proteins by cleaving peptide bonds within the protein chain, rather than at the ends. It is secreted by the pancreas and is a key component of pancreatic juice, which aids in digestion.

2. **Understanding the Reason (R)**:
- The reason states that "Trypsin acts on the interior peptide of a protein molecule."
- **Explanation**: This statement is accurate. As an endopeptidase, trypsin specifically targets peptide bonds located within the protein structure, breaking them down into smaller peptides. This action is crucial for the overall process of protein digestion.

3. **Evaluating the Truth of Both Statements**:
- Both the assertion (A) and the reason (R) are true.
- The assertion correctly identifies trypsin as an endopeptidase found in pancreatic juice, and the reason accurately describes its action on the interior peptide bonds of proteins.

4. **Conclusion**:
- Since both the assertion and the reason are true and the reason correctly explains the assertion, we conclude that both statements are correct and the reason provides a valid explanation for the assertion.

### Final Answer:
- Both the assertion (A) and the reason (R) are true, and the reason is a correct explanation of the assertion.
