in the light dependent photosynthetic reactions, light energy is converted into energy, which is stored in molecules like atp.

then, in the light independent photosynthetic reactions, this energy is used to convert co2 into

Chemical, glucose

Explanation:

In the light dependent photosynthetic reactions, light energy is converted into chemical energy, which is stored in molecules like ATP.  This occurs in the grana of the chloroplast.

Then, in the light independent photosynthetic reactions, this energy is used to convert CO2 into glucose. This occurs in the stroma.
