Light dependent reactions are directly dependent on light, but carbon reactions are dependent on products of light reaction.
The light-dependent reactions of photosynthesis are dependent on light energy hitting chlorophyll in photosystem II to allow photo-ionization of chlorophyll to occur. It produces ATP and NADPH (reduced NADP) through various processes.
The light-independent reaction (Calvin Cycle or C3 Pathway) does not rely on light BUT does require the products of the light-dependent reactions: ATP and NADPH. This allows reduction of GP to GALP which is then used to produce RuBP for future cycles and glucose too for respiration and cellulose production.
