The assimilatory and reducing powers synthesized in light reaction of photosynthesis are utilized in:
Correct answer: C. Reduction phase of Calvin cycle
- A. Fixation phase of Calvin cycle
- B. Regeneration phase of Calvin cycle
- C. Reduction phase of Calvin cycle
- D. Condensation phase of Calvin cycle
Explanation
The Calvin cycle consists of several phases, including the fixation, reduction, and regeneration phases. The reduction phase is where the assimilatory and reducing powers (ATP and NADPH) are utilized. In this phase, carbon dioxide (CO2) is converted into carbohydrate molecules (such as glucose) using the ATP and NADPH produced in the light reactions. This process involves the reduction of carbon dioxide and the incorporation of the energy and electrons from ATP and NADPH into the newly synthesized carbohydrate molecules.
