Enzyme found in saliva of Cockroach is

Options

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

Answer

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

### Step-by-Step Solution:

1. **Identify the Enzymes Present in Cockroach Saliva**:
- The saliva of a cockroach contains multiple enzymes, including amylase, cellulase, and chitinase.

2. **Understand the Function of Each Enzyme**:
- **Amylase**: This enzyme helps in the breakdown of carbohydrates. It is particularly important for digesting starches and sugars.
- **Cellulase**: This enzyme aids in the digestion of cellulose, which is a major component of plant cell walls. Since cockroaches are omnivorous, they consume plant material, making cellulase essential for their diet.
- **Chitinase**: This enzyme is responsible for breaking down chitin, which is found in the exoskeleton of arthropods and in fungal cell walls.

3. **Evaluate the Options Given**:
- The options provided are:
- A) Amylase
- B) Cellulase
- C) Chitinase
- D) All of the above
- Since all three enzymes (amylase, cellulase, and chitinase) are present in the saliva of cockroaches, we can conclude that the correct answer encompasses all of them.

4. **Select the Correct Answer**:
- Based on the analysis, the correct answer to the question is **D) All of the above**.
