Explanation:
The light reactions of photosynthesis use water and produce Oxygen, NADPH.
The equation for photosynthesis :
[tex]6 CO_2 + 6 H_2O[/tex] → [tex]C_6H_12O_6 + 6 O_2[/tex]
The process of photosynthesis in two stages -
For a light reaction -
Net Input is of, [tex]NADP^+[/tex], [tex]Light, Water, ADP[/tex]
Net Output is of, [tex]ATP, NADPH, O_2[/tex]
