when the atp synthase molecules are open, the hydrogen ions move out of
the thylakoid. how does the cell use the kinetic energy of the moving ions?

ok

explanation:

what's the question ?

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
