Explanation:
As electrons fall from photosystem ii to photosystem i, the cytochrome complex uses the energy to pump ions. this builds a proton gradient that is used in chemiosmosis to produce ATP.
In plants and cyanobacteria, a two-step mechanism known as noncyclic photophosphorylation results in the direct production of ATP and NADPH during photosynthesis. High-energy electrons exiting photosystem II are used in the noncyclic photophosphorylation process just outlined to produce ATP, which is then transferred to photosystem I to promote the creation of NADPH.
For every pair of electrons that move from H2O to NADP+ to create a molecule of NADPH, this results in the production of slightly more than one molecule of ATP.
