Question
Dark reaction in photosynthesis is called so because ______.
Options
It can occur in dark also
It does not depend on light energy
It cannot occur during day light
It occurs more rapidly at night
Solution
Dark reaction in photosynthesis is called so because it does not depend on light energy.
Explanation:
Splitting of the water molecule and formation of ATP is directly driven by light and hence are called light reactions. The rest of the steps are not directly light-driven and hence are called dark reactions (as per convention). This does not mean that they happen in the dark and not during the day.
