Electrons lose energy as the move down the electron transport chain
- The electrons lose energy as they move down the electron transport chain
- This is used to transport protons into the thylakoid to ensure there is a higher concentration of protons, compared to the stroma.
- Protons move down the concentration gradient via ATP synthase embedded in the thylakoid membrane.
- This combines ADP and Pi to form ATP
- This is called phosphorylation.
