What Is The Difference Between Light And Dark Reaction
Light reactions of photosynthesis directly depends on light. The pigments absorb light energy to produce ATP and NADPH. It includes, Light absorption Water splitting Oxygen release Formation of ATP and NADPH, which is then used in the biosynthetic phase.
Dark reaction or light independent reaction of photosynthesis utilize ATP and NADPH produced from light reactions are used for synthesising the food. CO2 is fixed to form fixation product. The reaction involved in the biosynthetic phase takes place in the stroma of chloroplasts.
