Hydrolysis of protein in the stomach and interstine takes place due to presence of the enzymes

Options

A. trypsin and pepsin respectively
B. pepsin and trypsin respectively
C. trypsin in both cases
D. pepsin in both cases

Explanation

To answer the question regarding the hydrolysis of proteins in the stomach and intestine due to the presence of enzymes, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Hydrolysis of Proteins**:
- Hydrolysis is a chemical process that involves the breakdown of proteins into smaller peptides or amino acids by the addition of water. This process is essential for digestion.

2. **Enzymes in the Stomach**:
- In the stomach, the primary enzyme responsible for protein hydrolysis is **pepsin**. Pepsin is secreted as an inactive precursor called pepsinogen, which is activated in the acidic environment of the stomach.

3. **Enzymes in the Intestine**:
- In the intestine, the enzyme that continues the process of protein hydrolysis is **trypsin**. Trypsin is produced in the pancreas and released into the small intestine, where it further breaks down proteins into smaller peptides.

4. **Summary of Enzymes**:
- Therefore, the enzymes responsible for the hydrolysis of proteins are:
- **Pepsin** in the stomach
- **Trypsin** in the intestine

5. **Final Answer**:
- The answer to the question is that the hydrolysis of proteins in the stomach occurs due to **pepsin**, and in the intestine, it occurs due to **trypsin**.
