Protons move into the thylakoid due to the

• concentration gradient in the stroma

•   Brownian motion of the protons.

•   peer pressure of the cool electrons in the stroma.  

• movement of electrons through the electron transport chain

The energy required to pump H⁺ ions into the H⁺ ion reservoir comes from the _____________

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.
