Here are the steps of the light reaction of photosynthesis arranged in the correct order:

  1. Photosystem II receives photons in the form of light energy.
  2. Light energy is transferred to a chlorophyll reaction center where electrons become energized.
  3. Electrons from the reaction center become energized and escape Photosystem II, moving down the electron transport chain.
  4. A protein in the electron transport chain pumps H+ ions from the stroma into the thylakoid space.
  5. Water is split to replace the electrons lost in Photosystem II.
  6. Electrons move down the electron transport chain, releasing energy.
  7. Electrons from the electron transport chain replace the electrons lost in Photosystem I.
  8. Electrons from Photosystem I become energized and move down a second electron transport chain.
  9. At the end of the electron transport chain, the energized electrons and H+ ions are used to reduce NADP+ to NADPH.
  10. H+ ions flow down their concentration gradient through ATP synthase, releasing energy in the process.
  11. ATP synthase uses energy to add a phosphate group to ADP, forming ATP.

This sequence highlights the key events in the light-dependent reactions of photosynthesis that take place in the thylakoid membranes of chloroplasts.
