6 O2 molecules, 12 NADPH molecules, and 18 ATP molecules are produced when 12 water molecules complete the light-dependent reactions.
What are light-dependent reactions?
In the presence of sunshine, light-dependent processes take place in the thylakoid membrane of the chloroplasts. These processes transform the solar energy into chemical energy. The photosynthesis process is carried out by the photosystem, which receives energy from the sun through the chlorophyll in plants.
They need light to function, and their overall conversion of water molecules to oxygen produces ATP molecules from ADP and Pi and NADPH molecules from the reduction of NADP+. The Calvin cycle can employ the ATP and NADPH that are created on the stroma side of the thylakoid membrane.
The "normal" form of the light-dependent processes, known as non-cyclic photophosphorylation, involves the removal of electrons from water and their passage via PSII and PSI before arriving at NADPH. Light must be absorbed twice throughout this process, once in each photosystem, in order to produce ATP. In fact, it uses light energy (photo) to create ATP from ADP, hence the name "photophosphorylation" (phosphorylation).
