NGSS.HS-LS2-5

Match the following parts of water with their function in light dependent reactions.

• Hydrogen Ions (H+)

• Replace those that were used in the chlorophyll at photosystem II

• Electrons (e-)

• Released as a byproduct

• Oxygen

• Build up in the thylakoid space to create a concentration gradient that will cause ATP synthase to rotate and add a phosphate to ADP to form ATP

When water breaks down, hydrogen ions are built up in the thylakoid space to create a concentration gradient for ATP Synthase. Mark the location where additional H+ are added.

At the end of the electron transport chain, electrons are picked up by the electron carrier to form NADPH which will then go to light-independent reactions.
