What is the primary product of light independent reactions
SOVA2 [1]

The primary products of the light independent reactions  (after one turn of the cycle) are:

a)  two G3P molecules

b)  three ADP

c) two NADP+

However ADP and NADP+ are not really "products". They are regenerated and later used again in the Light-dependent reactions.  Each G3P molecule is composed of three carbons.

For the Calvin cycle (Light independent cycle) to continue, 5 out of  the 6 carbons provided by the two G3P molecules are used to regenerate ribulose 1, 5 phosphate. Therefore there  remains only one carbon for the next turn of the cycle.

One  molecule of glucose requires 6 turns of the cycle. Any extra G3P is used to make starch, sucrose and cellulose.
