Which is the stable intermediate of photosynthesis

Options

A. glucose
B. formaldehyde
C. phosphoglyceric acid
D. phosphoglyceraldehyde

Answer

**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 in the form of glucose. This process occurs mainly in the chloroplasts of plant cells.

2. **Identifying the Products of Photosynthesis**: The primary products of photosynthesis are carbohydrates, which include sugars. These carbohydrates serve as energy sources for the plant and are crucial for growth and development.

3. **Recognizing Intermediates in Photosynthesis**: During the process of photosynthesis, several intermediate compounds are formed. These intermediates are essential for the conversion of light energy into stable chemical energy.

4. **Determining the Stable Intermediate**: The first stable intermediate product formed during the Calvin cycle of photosynthesis is Phosphoglyceric Acid (PGA). This compound is a 3-carbon molecule and is also referred to as 3-Phosphoglycerate.

5. **Conclusion**: Based on the information gathered, we can conclude that the stable intermediate of photosynthesis is Phosphoglyceric Acid (PGA).

**Final Answer**: The stable intermediate of photosynthesis is Phosphoglyceric Acid (PGA).
