Detailed explanation-1: -In non-cyclic photophosphorylation the photolysis of water produces electrons that generate a proton motive force which is used to produce ATP, the electrons finally being used to reduce NADP+ to NADPH.
Detailed explanation-2: -A molecule of water splits to release an electron, which is needed to replace the one donated. Oxygen and hydrogen ions are also formed from the splitting of water. The replacing of the electron enables chlorophyll to respond to another photon.
Detailed explanation-3: -Non-cyclic photophosphorylation is a process that results in the movement of the electrons in a non-cyclic way to synthesize the ATP molecules by using the energy from the excited electrons that are provided by Photosystem II.
Detailed explanation-4: -In photosynthesis, a light-dependent reaction uses light energy from the sun to split water which has been taken in by the organism. Water, when split, gives oxygen, hydrogen, and electrons. These electrons move through structures in chloroplasts and, by chemiosmosis, make ATP.
