Question

In photosynthesis, the set of reactions that use NADPH and ATP formed in the light-capturing reactions to drive the fixation of CO2, reduction of the fixed carbon to produce sugar, and the regeneration of the substrate used to fix CO2.

Answer 1

The correct answer will be- light independent reaction or Calvin cycle

Step-by-step explanation:

The process of photosynthesis takes place in the two phases: light-dependent and light-independent phase.

The light-dependent phase form NADPH and NADPH which are utilized during the light-independent phase to synthesise glucose molecule.

The light-independent phase occurs in the cytosol or stroma of the chloroplast in dark conditions which help synthesize the glucose molecules. The light-independent reaction is also known as the Calvin cycle which forms the glucose molecules in three steps- carboxylation, reduction and regeneration.

Thus, the Calvin cycle is the correct answer.
