Question

These steps are associated with the light reaction of photosynthesis. Place them in the correct order. H+ atoms pass through ATPase proton pump where the released energy helps make ATP Light energy from the sun is captured by chlorophyll in photosystem II (PSII) The split water makes H+ and oxygen The electron flows through protein complexes and loses energy as it flows The electron provides the energy to add an H+ to NADP+ to make NADPH B The H+ builds up in the thylakoid lumen and oxygen is released An electron s excited and passed to PQ The electron is energized at PSI from the light energy Water is split and donates an electron (e-) to replace the excited electron from PSII

Explanation / Answer

1)Light energy from the sun is captured by chlorophyll in photosystem II (PSII)

2) Water is split and donates an electron (e-) to replace the excited electron from psII

3)The split water makes H+ and oxygen

4)The H+ builds up in the thylakoid lumen and oxygen is released

5) H+ atoms pass through ATPase proton pump where the reeased energy helps make ATP

6)An electron is excited and passed to PQ

7) The electron flows through protein complexes and loses energy as it flows

8) The electron is energized at PSI from the light energy

9) The electron provides the energy to add an H+ to NADP+ to make NADPH
