In bacteria the site for respiratory activity is found in

Options

A. episome
B. mesosome
C. ribosome
D. microsome

Explanation

To answer the question "In bacteria, the site for respiratory activity is found in," we can follow these steps:

### Step 1: Understand the Question
The question is asking for the specific site within bacterial cells where respiration occurs.

### Step 2: Analyze the Options
We have four options to consider:
1. Epizomes
2. Mesosomes
3. Ribosomes
4. Microsomes

### Step 3: Evaluate Each Option
- **Epizomes**: These are extra chromosomal DNA in bacteria, not involved in respiration. Therefore, this option is incorrect.

- **Mesosomes**: These are invaginations of the bacterial cell membrane and are known to contain respiratory enzymes. They play a significant role in the respiratory activity of bacteria. This option is a strong candidate for the correct answer.

- **Ribosomes**: These are the sites of protein synthesis, not respiration. Thus, this option is also incorrect.

- **Microsomes**: These are fragments of the endoplasmic reticulum and are not found in bacteria. Therefore, this option is incorrect as well.

### Step 4: Identify the Correct Answer
After evaluating all the options, we conclude that the correct answer is **Mesosomes**, as they are involved in the respiratory processes in bacteria.

### Final Answer
The site for respiratory activity in bacteria is found in **Mesosomes**.
