Where do the electrons come from to start the electron transport chain?

• Oxygen

• ATP

• NADH and FADH2

• Water

Make a Prediction: Where will the electrons end?

Remember: in the first step of photosynthesis (the light reactions), the electrons came from the splitting of water and ended on the electron carrier, NADPH.
