Chemiosmosis

It serves pretty much the same aim, i.e. production of energy by ATPase. One can thing about it as being flipped (inside-out) in comparison to mitochondria or as analogy with cristae being stroma. One more thing that came to my mind. RuBISCO is activated ...

... RuBISCO in plant cells. Concentration gradient is gradient of concentration. If you do not understand to any of these words, look them up. The ATPase uses difference of hydrogen concentrations to synthesise ATP. C'mon, you really cannot find electron transport chain? :roll: Because the enzymes ...
