What does light do when it strikes the chlorophyll molecules of photosystems I and II?

• Light causes glucose to be synthesized directly inside the chlorophyll molecules of the photosystems.

• Light causes electrons to get excited (gain energy) and travel down the electron transport chain embedded in the thylakoid membrane.

• Light causes the conversion of water into carbon dioxide, oxygen, and electrons.

• Light directly causes carbon dioxide to attach to RuBP during the carbon fixation stage of the Calvin Cycle.

After the electron from photosystem I is transferred to the primary electron acceptor, it is passed along the electron transport chain by the carrier

• Plastoquinone

• Plantacyanin

• Cytochrome complex

• Ferredoxin

As the excited electrons lose energy along the electron transport chain, they are fueling the process of:

• Light capturing event

• Chemiosmosis

• Photolysis
