The light reactions of photosynthesis supply the calvin cycle with ATP and NADPH.

Explanation:

In the light reaction the energy from photons present in the sunlight is used to split water into oxygen, hydrogen ions, and electron. These electrons moves through the electron transport chain and produce chemical energy in the form of ATP and  NADPH.

This ATP and NADPH is supplied to the Calvin cycle and the energy released by these molecules is used to convert carbon dioxide into glucose molecules with the help of the enzyme RuBisCo. As Calvin cycle does not require light, therefore, it is a light-independent reaction.

Therefore the light reactions of photosynthesis supply the Calvin cycle with ATP and NADPH.
