These four Photosystem II, Cytochrome b6 f, Photosystem I and ATP synthase integral membrane complexes are vectorially oriented in the thylakoid membrane to function as follows, find out the incorrect statements;

#Unit 6. System Physiology – Plant
  1. Photosystem II oxidizes water to O2 in the thylakoid lumen and in the process releases protons into the lumen
  2. Cytochrome b6 f receives electrons from PSI and delivers them to PSII It also transports additional protons into the lumen from the stroma
  3. Photosystem I reduces NADP+ to NADPH in the stroma by the action of ferredoxin (Fd) and the flavoprotein ferredoxin–NADP reductase (FNR)
  4. ATP synthase produces ATP as protons diffuse back through it from the lumen into the stromaprotein ferredoxin–NADP reductase
