Question

where are the ATP and NADPH used???????

Answer 1

Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts). This illustration shows that ATP and NADPH produced in the light reactions are used in the Calvin cycle to make sugar.

Answer 2

they are used in light independent reactions... H from NADPH forms glucose with the help of CO2
