Reduction of CO2 into carbohydrates during photosynthesis can take place in the absence of light.Why?
- During light reaction or photochemical reaction of photosynthesis, the light energy obtained from sunlight is converted into chemical energy.
- This chemical energy is trapped in ATP and NADPH molecules which act as assimilatory power.
- This chemical energy is finally stored in carbohydrate molecules when ATP and NADPH are utilised in the dark reaction of biochemical phase of photosynthesis, thereby reducing CO2 to carbohydrates.
