The membrane inside the thylakoid of the chloroplast pumps H+ ions from the outside compartment (stroma) to the inside (lumen). This builds the gradient. The electrons are pumped using energy released from a high energy electron which was energized through light absorption. This electron comes from the breakdown of water.

when the membrane inside the thylakoid of a chloroplast pumps h+ ions from the outside (stroma) to the inside (lumen), it builds the gradient.
The energy is used to supply electron carriers and to pump protons into the stroma so they can come down their concentration gradient through an ATP-synthase and synthesize ATP.
Chemiosmosis, the diffusion of hydrogen ions on a selectively permeable membrane.
H+ ions (protons) are built into a gradient.
Protons released into the membrane travel through the proton gradient. Then thorugh the ATP synthase, the proteins are pumped out. Through phospholyration, ADPistranformed into ATP.
Then there will be no build up of protons in the outer lumpen of the mitochondria. Without a heavy concentration of hydrogen ions ( protons ) there there will be no moment of hydrogen ions down their concentration gradient through the ATPase pump and no ATP generated.

Cellular respiration.
The concentration gradient of protons is potential energy and is harnessed by an enzyme called ATP synthase. ATP synthase converts the potential energy of the proton concentration gradient into chemical energy stored in ATP (the process is called chemiosmosis). So without the protons, no ATP would be made, and therefore no light reaction would occur.
If the protein is pumping protons, there should be an electrical gradient across the membrane as well as a proton concentration gradient.
phosphorylation of ADP to ATP occurring when protons that follow a concentration gradient contact ATP synthase.
The energy is used to supply electron carriers and to pump protons into the stroma so they can come down their concentration gradient through an ATP-synthase and synthesize ATP.
matrix. to create a concentration gradient
To provide the motive force that pumps protons into the outer lumen of the mitochondria. Where the protons will fall down their concentration gradient through the ATP synthase and generate ATP.
Chemiosmosis, the diffusion of hydrogen ions on a selectively permeable membrane.
A concentration gradient is a representatinve of energy storage. ATP the energy currency of the cell will require this conc. gradient for its formation. HIgher the conc. gradient the higher will be the stored energy and high the no of ATP can be formed.
NH3 enters the thylakoid lumen and eats the protons, by binding them it and decreases the proton gradient compared to the outside of the lumen. This "uncouples" the proton motive and reduces ATP synthesis
