Isolated metabolism reaction outside the body performed in test tube is/are

Options

A. Living
B. Non - living
C. Neither living nor non-living
D. Both (a) and (b)

Answer

To answer the question "Isolated metabolism reaction outside the body performed in test tube is/are", we will follow these steps:

### Step-by-Step Solution:

1. **Understanding the Context**:
- The question refers to metabolic reactions that occur outside of a living organism, specifically in a test tube. This indicates that we are dealing with reactions that are performed in vitro (outside the body).

2. **Defining In Vitro**:
- In vitro refers to biological processes or reactions that are conducted in a controlled environment outside of a living organism, such as a test tube or petri dish.

3. **Nature of the Reaction**:
- Metabolism encompasses all chemical reactions that occur within living organisms to maintain life. These reactions involve biomolecules and are essential for processes such as energy production, growth, and reproduction.

4. **Characterizing the Reaction**:
- When metabolic reactions are performed in vitro, they are not occurring within a living cell or organism. Therefore, they do not exhibit the characteristics of living systems, even though they involve biological molecules.

5. **Conclusion**:
- Since the metabolic reactions are taking place outside of a living system (in vitro), they cannot be classified strictly as living or non-living. They are biochemical reactions that are isolated from the living context. Thus, the correct classification for these reactions is "neither living nor non-living".

### Final Answer:
The isolated metabolism reaction outside the body performed in a test tube is **neither living nor non-living**.
