Explain how during light reaction of photosynthesis, ATP synthesis is

1.	Explain how during light reaction of photosynthesis, ATP synthesis is a chemiosmotic phenomenon.
Answer» The conditions helpful in chemiosmotic ATP synthesis are: 1. The splitting of the water molecule takes place on the inner side of the membrane, it causes the accumulation of protons or hydrogen ions within the lumen of the thylakoids. 2. As electrons move through the photosystems, protons are transported across the membrane, and proton is released into the inner side or the lumen side of the membrane. 3. The NADP reductase enzyme is located on the stroma side of the membrane. Along with electrons that come from the accepter of electrons of PS I, protons are necessary for the reduction of NADP⁺to NADPH⁺ H⁺. These protons are also removed from the stroma.
