Answer:
The correct answer is option B, that is, Calvin cycle.
Step-by-step explanation:
The light-independent reaction or photosynthetic carbon reduction of photosynthesis is termed as the Calvin cycle. In this reaction, the compounds get transformed to glucose, and at the same time regenerated ribulose bisphosphate gets produced as the end product with ADP from ATP.
ADP is obtained from the molecules of ATP, and 1 molecule of glucose is generated as the end product in the reduction phase of the process. On the other hand, in the regeneration phase, the molecules of RuBP regenerates and the molecules of ATP get convert again to the molecules of ADP.
