Enzymes required for photophosphorylation are located in ......... Of chloroplast

Options

A. Peristromium
B. Plastidome
C. Stroma
D. Quantasome.

Answer

**Step-by-Step Solution:**

1. **Understanding Photophosphorylation**: Photophosphorylation is a process that occurs during the light reactions of photosynthesis, where ATP (adenosine triphosphate) is produced using light energy.

2. **Identifying the Site of Light Reactions**: The light reactions of photosynthesis take place in the thylakoids of the chloroplast. The thylakoids are membrane-bound structures that contain chlorophyll and other pigments necessary for capturing light energy.

3. **Role of Thylakoid Membranes**: The thylakoid membranes are equipped with proteins and complexes, including quantosomes, which are essential for the photophosphorylation process. These structures help in the conversion of light energy into chemical energy in the form of ATP.

4. **Conclusion**: Therefore, the enzymes required for photophosphorylation are located in the thylakoid membranes of the chloroplast.

**Final Answer**: The enzymes required for photophosphorylation are located in the **thylakoids** of chloroplasts.
