ATP synthesis is linked to-
1. Development of electron gradient
2. Development of atomic gradient
3. Development of proton gradient
4. Flow of electrons across the membrane
The difference in development of proton gradient in photosynthesis and respiration is-
| 1. | Photosynthesis has thylakoid membrane across which proton gradient is generated |
| 2. | Proton accumulation is inside the membrane of thylakoid. |
| 3. | both a and b |
| 4. | Mitochondrial membrane is involved |
What does not cause the proton gradient across the membrane?
1. Splitting of water
2. Moving electrons through photosystems
3. Reduction of NADP
4. Q cycle
Where does the splitting of water take place?
1. Stroma
2. Cytoplasm
3. Thylakoid lumen
4. Plasma membrane
