The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Light Reactions**: The light reactions of photosynthesis are processes that convert light energy into chemical energy. This occurs in the chloroplasts of plant cells. 2. **Location of ATP Synthesis**: The synthesis of ATP during light reactions takes place specifically in the chloroplasts. Within the chloroplasts, there are structures called thylakoids. 3. **Photophosphorylation**: The process by which ATP is formed during the light reactions is known as photophosphorylation. This process involves the conversion of light energy into ATP. 4. **Thylakoid Membrane**: The thylakoid membrane is crucial for the light reactions. The ATP synthesis occurs on the stromal side of the thylakoid membrane. 5. **Conclusion**: Therefore, the correct answer to the question about the site of ATP synthesis during the light reactions is the stromal side of the thylakoid membrane. **Final Answer**: The site for the synthesis of ATP in the light reaction is the **stromal side of the thylakoid membrane**. ---
