Respiration is an

Options

A. Endothermic process
B. Exothermic process
C. Anabolic process
D. Endergonic process

Answer

**Step-by-Step Solution:**

1. **Understanding Respiration**: Respiration is a biochemical process that occurs in living organisms to convert food into energy. It involves the breakdown of glucose in the presence of oxygen.

2. **Identifying the Nature of Respiration**: The question asks about the nature of respiration. We need to determine whether it is endothermic, exothermic, anabolic, or endogonic.

3. **Analyzing the Options**:
- **Endothermic Process**: This type of process absorbs heat or energy from the surroundings. It is not applicable to respiration since respiration releases energy.
- **Exothermic Process**: This process releases heat or energy into the surroundings. Respiration fits this category as it releases energy when glucose is broken down.
- **Anabolic Process**: Anabolic processes are those that build complex molecules from simpler ones, often requiring energy. Respiration does not fit this definition as it breaks down molecules.
- **Endogonic Process**: This is a heat-absorbing reaction that is non-spontaneous. Respiration does not absorb heat; it releases it.

4. **Conclusion**: Since respiration releases energy, it is classified as an exothermic process. Therefore, the correct answer is **exothermic process**.
