What are products of the light reactions of photosynthesis that are utilized in the calvin cycle?

ATP and NADPH

Explanation:

The photosynthesis involves two stages: the light-dependent reactions and the Calvin cycle.

The first stage is called the light-dependent reactions, in which the chlorophylls convert the light energy from the sun into two storage molecule energy, namely ATP (Adenosine triphosphate) and NADPH (energy-carrying molecule). In this stage, the water is converted to oxygen gas.      

The second stage is known as the Calvin cycle, in which the transformation of the carbon from the carbon dioxide into glucose requires the use of ATP and NADPH from the light-dependent reactions.                

Therefore, the products of the light reactions of photosynthesis that are utilized in the Calvin cycle are ATP and NADPH.
