Some proteolytic enzymes are-

Options

A. Trypsin,Erepsin,Pepsin
B. Amylase,Lipase,Zymase
C. Ampylopsin,Steapsin,Ptyalin
D. Urease,Dehydrogenase,Zymase

Answer

### Step-by-Step Solution:

1. **Understanding Proteolytic Enzymes**: Proteolytic enzymes, also known as proteases or proteinases, are enzymes that break down proteins into smaller peptides or amino acids. They play a crucial role in the digestion of dietary proteins.

2. **Identifying the Enzymes**: The question lists several enzymes, and we need to determine which of them are proteolytic. The enzymes mentioned in the first option are trypsin, erepsin, and pepsin.

3. **Analyzing Each Enzyme**:
- **Trypsin**: This enzyme is produced in the pancreas and is secreted into the small intestine. It breaks down proteins into smaller peptides (dipeptides).
- **Erepsin**: This is a mixture of proteolytic enzymes found in the intestinal juice. It further digests peptones into amino acids.
- **Pepsin**: This enzyme is secreted by the stomach and begins the digestion of proteins by converting them into smaller peptides (peptones).

4. **Conclusion on the First Option**: Since all three enzymes (trypsin, erepsin, and pepsin) are involved in protein digestion, the first option is correct.

5. **Evaluating Other Options**:
- **Second Option (Amylase, Lipase)**: Amylase digests carbohydrates, and lipase digests fats. Therefore, this option is incorrect as neither enzyme digests proteins.
- **Third Option (Amylopsin, Steapsin, Tylenol)**: Amylopsin breaks down starch, steapsin digests fats, and Tylenol is not an enzyme related to digestion. Hence, this option is also incorrect.
- **Fourth Option (Urease, Dehydrogenase, Zymase)**: Urease hydrolyzes urea, dehydrogenase is involved in oxidation-reduction reactions, and zymase ferments sugars. None of these are proteolytic enzymes, making this option incorrect as well.

6. **Final Answer**: The only correct option that lists proteolytic enzymes is the first one: **Trypsin, Erepsin, and Pepsin**.
