What are the products of light-dependent reactions? why are they important in light-independent reactions?

Answer;

ATP and NADPH are the products of light-dependent reactions.

These products (ATP and NADPH) are used in  the light-independent reactions to make sugar.

Explanation;

-Photosynthesis can be divided into two parts: the light-dependent reactions and the light-independent reactions.

-The two products of the light-dependent reactions of photosystem are ATP and NADPH. The movement of high energy electrons releases the free energy that is needed to produce these molecules. The ATP and NADPH are used in the light-independent reactions to make sugar.

-Light-independent reactions uses products of the light-dependent reactions (ATP and NADPH) and various enzymes. Therefore, the light-independent reaction cannot happen without the light-dependent reaction.
