What molecules produced during the light reaction of photosynthesis are needed to carry out the dark reaction?

ATP  and  NADPH   molecules  produced  during the light   light  reaction  of  photosynthesis  are  needed  to  carry   out  the   dark  reaction.

  During  the  dark  stage  of   photosynthesis  ATP  and  NADPH  molecules  produced  during  the  light  stage  is  used  in the  dark  stage  to  fix  carbon  dioxide(CO2).  The   dark  stage  reaction  produces  sugar  molecules   and  other  organic  molecules  necessary   for cell function  and  metabolism

Most smaller stars don't have a radiative zone.

The real answer is keeping the world healthy so we won’t die
