Question

The primary function of the light-independent reaction in photosynthesis is

• A. to synthesize ATP and NADPH
• B. to provide food to plant in form of glucose
• C. to produce carbon dioxide
• D. all of these

Answer 1

The correct option is B to provide food to plant in form of glucose

ATP and NADPH are assimilatory powers formed during light dependent reaction. The products (ATP and NADPH) of the light-dependent reactions are used during the light-independent reactions to reduce carbon dioxide and convert the energy to the chemical bond energy in carbohydrates such as glucose. Hence, the primary function of a light-independent reaction is to synthesize glucose.
