Options

A. Dutrochet
B. Warburg
C. Pasteur
D. J.C. Bose

Answer

To solve the question "Who is not connected with respiration?" we will analyze each of the given options step by step.

### Step-by-Step Solution:

1. **Identify the Options**: The question provides four options, which we need to evaluate to determine which one is not connected with respiration.

2. **Evaluate Option 1: Dutrochet**:
- Henri Dutrochet was a French physiologist known for his contributions to the understanding of respiration in both animals and plants. He coined the term "respiration."
- **Conclusion**: Dutrochet is connected with respiration.

3. **Evaluate Option 2: Vagbhata**:
- Vagbhata is known for his contributions to medicine and physiology, particularly in the context of ancient Indian medicine. He proposed a hypothesis linking insufficient cellular respiration to tumorogenesis.
- **Conclusion**: Vagbhata is connected with respiration.

4. **Evaluate Option 3: Pasteur**:
- Louis Pasteur is famous for his work on fermentation and the Pasteur effect, which describes how glycolysis is linked with respiration. His research significantly advanced the understanding of microbial respiration.
- **Conclusion**: Pasteur is connected with respiration.

5. **Evaluate Option 4: J.C. Bose**:
- Jagadish Chandra Bose was a physicist and biologist known for his work in plant physiology, but he is not primarily associated with the study of respiration. His research focused more on plant responses to stimuli rather than respiration.
- **Conclusion**: J.C. Bose is not connected with respiration.

### Final Answer:
The correct answer is **Option 4: J.C. Bose**, as he is not connected with respiration.
