Why does darkness affect the light-independent reactions of photosynthesis?
notsponge [240]

Answer:

The correct answer would be Light independent reactions require the energy gathered in the thylakoids.

Photosynthesis can divided into two sub-processes or reactions:

Light-dependent reaction: It converts solar energy into chemical energy that is, ATP (adenosine triphosphate) and NADPH with the help of photolysisis of water. It takes place in thyllakoid membrane of the chloroplast.

Light-independent reaction: It fixes carbon obtained from carbon dioxide into the food or glucose with the help of enzyme RuBisCO (Ribulose-1,5-bisphosphate carboxylase/oxygenase).

It takes place in the stroma of the chloroplast and does not require the involvement of light however, it requires the products (ATP and NADPH) of the light reaction.

Fixation of 1 molecule of glucose requires 6 molecules of carbon dioxide, 9 molecules of ATP and 6 molecules of NADPH.

So, darkness indirectly affects the light-independent reaction.
