what happens to the carbon atom during photosynthesis in the light-dependent reactions and the light-independent reactions?

Question

Light-dependent reaction 
The exergonic (energy-releasing) light-dependent reactions of photosynthesis convert light energy into chemical energy, producing ATP and NADPH. These reactions occur in the grana (stacks of thylakoids) of the chloroplasts. The products of the light-dependent reactions, ATP and NADPH, are both required for the endergonic (energy-requiring) light-independent reactions. 

Light-independent reaction 
The endergonic (energy-requiring) light-independent reactions of photosynthesis use the ATP and NADPH synthesized during the exergonic (energy-releasing) light-dependent reactions to provide the energy for the synthesis of glucose and other organic molecules from inorganic carbon dioxide and water. This is done by "fixing" carbon atoms from CO2 to the carbon skeletons of existing organic molecules. These reactions occur in the stroma of the chloroplasts.
