Q. No.In the process of photosynthesis, electrons lost by Photosystem II (PS II) must be continuously replaced. Considering the location and function of the water-splitting complex associated with PS II, where are the protons (H⁺) and oxygen (O₂) released?
| 1. | Protons (H⁺) are released into the stroma, and O₂ is released into the lumen of the thylakoid. |
| 2. | Protons (H⁺) are released into the lumen of the thylakoid, and O₂ is released into the stroma. |
| 3. | Both protons (H⁺) and O₂ are released into the lumen of the thylakoid. |
| 4. | Both protons (H⁺) and O₂ are released into the stroma. |
