Question

How is light energy converted into chemical energy during photosynthesis?

Answer 1

The light energy is converted into the reduction of NADP and formation of ATP.

Explanation:

The light energy is converted into chemical enrgy. The most important by product of photosynthesis is oxygen. The other products are ATP and NADPH.
Photophophorylation is the formation of ATP in the presence of light. The photophosphorylation is cyclic and non-cyclic type.
Dark reactions make use of these organic energy molecules ATP and NADPH. This reaction cycle is also called Calvin Cycle after the name of its discovere Calvin Benison.
The ATP provides the energy to the Cycle, while the NADPH provides the electrons required to fix the CO2 into carbohydrates. Thank.
