The enzymes that are present in the saliva are

Options

A. Ptyalin, sucrose and amylase
B. Lysozyme , amylase and zymase
C. Amylase , sucrase and ptyalin
D. Ptyalin, lipase and lysozyme

Answer

To determine the enzymes present in saliva, let's analyze the given options step by step.

### Step 1: Identify the enzymes in saliva
Saliva contains several enzymes that aid in the digestion process. The most notable enzymes are:

- **Amylase**: This enzyme breaks down starch into simpler sugars like maltose and dextrin.
- **Lysozyme**: This enzyme has antibacterial properties and helps in breaking down bacterial cell walls.

### Step 2: Evaluate the options provided
Now, let's evaluate the options one by one:

1. **Option 1: Patalene, Sucrose, and Amylase**
- **Patalene**: This seems to be a misspelling of "Ptyalin," which is another name for salivary amylase.
- **Sucrose**: This is not an enzyme; it is a sugar.
- **Amylase**: Correctly identified as present in saliva.
- **Conclusion**: This option is incorrect due to the presence of sucrose.

2. **Option 2: Lysozyme, Amylase, and Zymase**
- **Lysozyme**: Correctly identified as present in saliva.
- **Amylase**: Correctly identified as present in saliva.
- **Zymase**: This is not present in saliva; it is an enzyme complex involved in fermentation.
- **Conclusion**: This option is incorrect due to the presence of zymase.

3. **Option 3: Amylase, Sucrase, and Patalene**
- **Amylase**: Correctly identified as present in saliva.
- **Sucrase**: This enzyme is involved in the digestion of sucrose and is produced in the small intestine, not in saliva.
- **Patalene**: Again, this seems to refer to ptyalin (amylase).
- **Conclusion**: This option is incorrect due to the presence of sucrase.

4. **Option 4: Patalene, Lipase, and Lysozyme**
- **Patalene**: Referring to ptyalin (amylase), which is present in saliva.
- **Lipase**: This enzyme is involved in fat digestion and is not primarily found in saliva.
- **Lysozyme**: Correctly identified as present in saliva.
- **Conclusion**: This option is incorrect due to the presence of lipase.

### Final Conclusion
None of the options provided are entirely correct, but the closest option that includes enzymes typically associated with saliva is **Option 4**, considering ptyalin (amylase) and lysozyme are indeed present in saliva.
