Photosynthesis Light Dependent Reaction

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 _____________

• ATP molecules

• Electron Transport Chain

• Light 

• Thylakoid Membrane
