During the light reaction, why are protons transported from the stroma toward the thylakoid lumen as electrons move through the electron-transport system?
- AThe primary electron acceptor transfers its electron to a hydrogen carrier that also carries a proton from the stroma.
- BWater is split on the stromal side of the thylakoid membrane.
- CNADP⁺ reductase pumps protons from the stroma into the lumen.
- DATP synthase pumps protons from the stroma into the lumen.
