Question

What the heck am I talking about when I say "Reduction of plastoquinone to plastoquinol occurs on the stroma side of the thylakoid membrane, and oxidation of plastoquinol back to plastoquinone occurs on the lumen side of the thylakoid membrane"? This describe: The proton motive force being used to convert ADP + Pi to ATP Splitting water (H_2 O) into molecular oxygen (O_2), 4H^+ and 4e^- Using the proton motive force to move electrons across the membrane Moving electrons down an energy gradient to move protons up a concentration gradient Excitation of electrons in chlorophyll of photosystem I and II to initiate photochemistry During the Calvin-Benson Cycle Light energy is converted and stored directly by reducing carbon dioxide and producing sugars Light energy is used to create chemical energy in the form of ATP and NADPH Chemical energy of ATP and NADPH is used to create a membrane potential Chemical energy of ATP and NADPH is used to reduce carbon dioxide to sugars Chemical energy of ATP and NADPH is used to oxidize carbon dioxide to sugars

Explanation / Answer

MOVING ELECTRONS DOWN AN ENERGY GRADIENT TO MOVE PROTONS UP CONCENTRATION GRADIENT . ....... because electrons are transferred to cytb6f complex while the protons are translocated to lumen side .

CHEMICAL ENERGY OF ATP AND NADPH IS USED TO REDUCE CARBONDIODXIDE TO SUGARS ..... because ATP and NADPH are produced in light reaction phase of photosynthesis .

Hope this helps feel free to comment and discuss ...... Regards
