Answer

To solve the question regarding the enzymes P, Q, R, and S in the protein digestion flowchart, we can break down the process step by step:

### Step-by-Step Solution:

1. **Identify Enzyme P**:
- The first step in protein digestion occurs in the stomach where proteins are broken down into proteoses and peptones.
- The enzyme responsible for this is **Pepsin**, which is derived from its inactive form, **Pepsinogen**.
- **P = Pepsin**.

2. **Identify Enzyme Q**:
- After the stomach, the partially digested proteins (proteoses and peptones) move into the small intestine.
- Here, pancreatic enzymes are activated to further digest these compounds into polypeptides.
- The enzyme that converts proteoses and peptones into polypeptides is **Trypsin**.
- **Q = Trypsin**.

3. **Identify Enzyme R**:
- The next step involves the breakdown of polypeptides into dipeptides.
- This process is facilitated by another pancreatic enzyme called **Chymotrypsin**.
- **R = Chymotrypsin**.

4. **Identify Enzyme S**:
- Finally, dipeptides are broken down into amino acids.
- This final step is carried out by the enzyme **Dipeptidase**, which is present in the intestinal lining.
- **S = Dipeptidase**.

### Summary of Enzymes:
- **P = Pepsin**
- **Q = Trypsin**
- **R = Chymotrypsin**
- **S = Dipeptidase**

### Final Answer:
The correct information of enzymes P, Q, R, and S is:
- P: Pepsin
- Q: Trypsin
- R: Chymotrypsin
- S: Dipeptidase
