Calvin Cycle
Light-independent reactions
During the Calvin cycle, or light independent reaction, plants use energy that NADPH and ATP contain to build high-energy compounds that can stored up to a long period of time.
Glencoe Science; BIOLOGYLight energy is absorbed and then converted into chemical energy in the form ofATP and NADPH. The ATP and NADPH that were formed in phase one are usedto make glucose.
To provide ATP and NADPH to drive the next part of photosynthesis, the Calvin Cycle (AKA Dark Reaction, Light Independent Reaction). Light reactions also produce oxygen gas as a byproduct.
It is not.The synthesis of sugar from CO2 and H20 requires the energy of light - it is therefore light dependent.
During the light-dependent reaction of photosynthesis, light energy is used to split water molecules to produce oxygen, ATP, and NADPH. These products are then used in the light-independent reaction (Calvin Cycle) to convert carbon dioxide into glucose.

Because this reaction proceeds without using light energy.
Light dependent reactions produce ATP and NADPH from energy captured from light. Therefore without light it cannot proceed. Light independent reactions fix carbon dioxide into glucose using the ATP and NADPH produced in the light dependent reactions. So light independent reactions can occur without light as long as CO2, ATP and NADPH is present.
The Light Reactions Provide Energy Carriers For The Dark Reactions.
In photosynthesis, the reactants of the light-dependent reaction are water and light energy, which are used to produce oxygen, ATP, and NADPH. The products of the light-independent reaction (Calvin cycle) are ATP, NADPH, and carbon dioxide, which are used to produce glucose through a series of enzymatic reactions. The light-dependent reaction occurs in the thylakoid membranes of chloroplasts, while the light-independent reaction takes place in the stroma of the chloroplast.
