Question

Biosynthetic reaction of photosynthesis is also called dark reaction because

• A. It occurs in dark
• B. It does not require light energy
• C. Both 1 and 2
• D. None of the above

Answer 1

The correct option is B It does not require light energy

During the light independent reaction or the Biosynthetic reaction, carbon dioxide from the atmosphere and energy genrated in the form of ATP and NADPH during the light dependent reaction are combined to form sugars such as glucose.
As light is not required for this reaction to occur, it is also called as Dark reaction.
