In photosynthesis, the light reactions converts the sunlight int chemical energy (ATP molecules, NADH+H). Dark reactions (light independent reactions) do not use sunlight directly, but use energy stored in ATP and NADH molecules combined with CO2 to produce sugars.

The Calvin Cycle, earlier designated the photosynthetic '''"dark reactions" pathway, is now referred to as the carbon reactions pathway. In this pathway, the free energy of cleavage of ~P bonds of ATP, and reducing power of NADPH, are used to fix and reduce CO2 to form carbohydrate. Enzymes and intermediates of the Calvin Cycle are located in the chloroplast stroma, a compartment somewhat analogous to the mitochondrial matrix. '''
