Options

A. catabolic exothermic, reductive process
B. anabolic endothermic, oxidative reductive process
C. both anabolic and catabolic process
D. a chemical process

Answer

To answer the question "Photosynthesis, a process of manufacture of organic compounds is," we need to analyze the options provided and understand the characteristics of photosynthesis.

### Step-by-Step Solution:

1. **Understanding Photosynthesis**:
- Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy stored in glucose. This process occurs mainly in the chloroplasts of plant cells.

2. **Identifying the Nature of Photosynthesis**:
- Photosynthesis is primarily an **anabolic process**. Anabolism refers to the synthesis of complex molecules from simpler ones, which is exactly what happens when plants convert carbon dioxide and water into glucose.

3. **Energy Requirement**:
- Photosynthesis is an **endothermic process**. This means it requires energy input (in the form of sunlight) to proceed. The energy from sunlight is absorbed by chlorophyll and used to drive the reactions that convert CO2 and H2O into glucose.

4. **Oxidation-Reduction Reactions**:
- Photosynthesis involves **oxidation-reduction (redox) reactions**. During this process, water is oxidized (loses electrons) to produce oxygen, and carbon dioxide is reduced (gains electrons) to form glucose. This indicates that both oxidation and reduction occur during photosynthesis.

5. **Conclusion**:
- Given the characteristics discussed, the correct answer to the question is that photosynthesis is an **anabolic, endothermic, oxidative-reductive process**. Therefore, the correct option is the second one.

### Final Answer:
Photosynthesis, a process of manufacture of organic compounds is an **anabolic endothermic oxidative reductive process**.
