Difference between Light and Dark Reaction
| Light Reaction | Dark Reaction |
|---|---|
| The end products are ATP and NADPH. | Glucose is the end product. ATP and NADPH help in the formation of glucose. |
| The water molecules split into hydrogen and oxygen. | Glucose is produced. Co2 is utilized in the dark reaction. |
Herein, what are the products of dark reactions?
The dark reaction occurs outside of the thylakoids. In this reaction, the energy from ATP and NADPH are used to fix carbon dioxide (CO2). The products of this reaction are sugar molecules and other organic molecules necessary for cell function and metabolism.
Hereof, what are the end products of light and dark reaction?
There are two end products of the light reaction of photosynthesis, ATP and NADPH. These molecules are produced during the cyclic and the non-cyclic photophosphorylation reactions. These are the products which are used in the dark reactions.
In this cycle ATP and NADPH, produced in the light stage, provide the energy and electrons to change carbon dioxide (CO2) to carbohydrates (C H O) molecules. Although this stage is called the dark stage it occurs in light and also in darkness as long as the products of the light phase are still available.
