Answer :
Final answer:
The molecule that is regenerated in the regeneration phase of the Calvin cycle is RuBP (ribulose-1,5-bisphosphate). Without the regeneration of RuBP, the Calvin cycle would not be able to continue. Therefore, the correct option is B.
Explanation:
In the regeneration phase of the Calvin cycle, the molecule that is regenerated is RuBP (ribulose-1,5-bisphosphate). Without the regeneration of RuBP, the Calvin cycle would not be able to continue.
During the regeneration phase, one G3P molecule leaves the cycle to contribute to the formation of carbohydrate molecules, while the remaining five G3P molecules are used to regenerate RuBP. ATP is also used in the regeneration reactions.
