Question

Do reactions of photosynthesis called ‘Dark Reaction’ need light? Explain.

Answer 1

Dark reaction

● Dark reaction in plants is the actual biosynthetic phase.
● $C{O}_2$ is reduced to form glucose by obtaining the energy from the breakdown of ATP and NADPH.
● ATP and NADPH are the products of the light reaction.

Thus, it can be concluded that a dark reaction is dependent on the products of the light reaction but independent of sunlight.
