No. |
Dark reaction |
Light reaction |
Definition |
||
1. | A reaction where the carbon dioxide and water molecules form sugar molecules in a light-independent process, then this is called as Dark reaction. | A photosynthetic process where light energy is of sun is converted into chemical energy in the form of ATP and NADPH, this is called as light reaction. |
Photolysis |
||
2. | During dark reaction, photolysis of water does not occurs. | During light reaction, photolysis of water occurs. |
Oxygen Or carbon dioxide |
||
3. | In the dark reaction, carbon dioxide is utilized. | In the light reaction, oxygen is released. |
Phase in the photosynthesis |
||
4. | In the photosynthesis, dark reaction is the second phase. | In the photosynthesis, light reaction is the first phase. |
End product |
||
5. | End product of dark reaction is glucose. | End products of light reaction are NADPH and ATP. |
Chlorophyll |
||
6. | For the dark reaction, chlorophyll is not required. | For the light reaction, chlorophyll is required. |
