Answer
In the Calvin cycle, carbon atoms from carbon dioxide are fixed into organic molecules and used to build smaller sugars. This process relies on ATP and NADPH from the light reactions. This reactions of the Calvin cycle takes place in the stroma. The Calvin cycle would not be able to take place if it were not for the products of the light reactions.
