NADPH
Light Reactions and the Calvin Cycle Reactions.
The light reactions provide the energy carriers used in the Calvin cycle
Calvin cycle or light independent reaction
The Calvin cycle is a series of reaction that regenerates its starting material after molecules enter and leave the cycle. It builds carbohydrates (specifically, the sugar glyceraldehyde-3-phosphate) from smaller molecules and consumes energy. To do this, the Calvin cycle uses ATP as an energy source and consumes NADPH as reducing power.
An easily understood explanation is: NADPH carries high-energy electrons that were produced by light absorption in chlorophyll to chemical reactions elsewhere in the cell. NADPH is a chemical compound which gives hydrogen atom for the formation of the carbohydrate in the dark reactions of the photosynthesis. Photosynthesis is completed in two steps: Light reactions dark reactions Another explanation: NADPH provides a source of hydrogen for reduction reactions in photosynthesis. In the light independent reactions carbon dioxide is converted into carbohydrate: CO2 --------> CH2O NADPH provides the hydrogen needed for this reaction.
Light Reactions and the Calvin Cycle Reactions.
because the Calvin cycle does not require light
Light-dependent reactions use light to create ATP and NADPH/Reduced NADP Which is used on the Calvin cycle so of it is not present the cycle cannot continue.
The main processes in the in dependant reactions are collectively called the Calvin Cycle.

Calvin Cycle
Comparing the light reactions with the Calvin cycle of photosynthesis, which requires CO2?
The light reactions produce NADPH, where the Calvin Cycle produces NADP+
