Answer:
The correct answer is option D. The Calvin cycle.
Explanation:
The Calvin cycle is the light-independent reaction or photosynthetic carbon reduction of photosynthesis. these are the reaction that converts other compounds to glucose and regenerates RuBP as the end product with ADP from ATP.
In the reduction phase, ADP converted from ATP molecules and one glucose molecule is produced as the end product. In the regenration phase, the RuBP molecule regenerates and ATP molecules convert again in ADP molecules.
Thus, the correct answer is option D. T Calvin cycle
