Answer :
Final answer:
During the regeneration phase of the Calvin cycle in photosynthesis, RuBP is regenerated from G3P. RuBP is crucial for continuing the cycle of carbon fixation. Therefore, the produced compound during this process is RuBP.
Explanation:
Light Independent Reactions in Photosynthesis
The process of photosynthesis involves two main stages: the light-dependent reactions and the light-independent reactions, also known as the Calvin cycle. Within the Calvin cycle, several compounds are produced and utilized, one of which is RuBP (ribulose bisphosphate). During the regeneration phase of the Calvin cycle, RuBP is regenerated from G3P (glyceraldehyde-3-phosphate) to continue the process of carbon fixation.
To break this down:
- PGA (phosphoglycerate) is an earlier product that is not regenerated.
- G3P is a direct product of the Calvin cycle that can be used to form glucose but is also a precursor in the regeneration of RuBP.
- RuBP is the acceptor molecule that is necessary to restart the Calvin cycle.
- Rubisco is the enzyme that catalyzes the conversion of carbon dioxide and RuBP to PGA but is not itself a product of regeneration.
Thus, the correct answer to the question of which compound is produced during regeneration is RuBP.
