Enzyme found in saliva of Cockroach is

Options

A. Amylase
B. Cellulase
C. Protease
D. All the above

Answer

To determine the enzyme found in the saliva of a cockroach, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for the specific enzyme present in the saliva of a cockroach.

2. **Identify the Options**: The options given are:
- Amylase
- Cellulase
- Protease
- All of the above

3. **Research the Salivary Enzymes of Cockroaches**:
- Cockroaches produce saliva that contains various enzymes.
- One of the primary enzymes found in cockroach saliva is **amylase**, which helps in the breakdown of starches into sugars.

4. **Consider Other Enzymes**:
- While amylase is present, cockroach saliva may also contain **cellulase** (which breaks down cellulose) and **chitinase** (which breaks down chitin), but these are not the primary enzymes associated with their saliva.
- **Protease** is typically involved in protein digestion and is not a primary enzyme found in cockroach saliva.

5. **Evaluate the Options**:
- Since amylase is a known enzyme in cockroach saliva, and the other options (while they may be present in some form) are not the main focus, the best answer is **amylase**.

6. **Final Answer**: The enzyme found in the saliva of cockroach is **amylase**.
