Final answer:
Ribulose-1,5-bisphosphate (RuBP) is the compound produced during the regeneration stage of the Calvin cycle in photosynthesis. This allows for the continued fixation of CO2.
Explanation:
The compound that is produced during regeneration in the Calvin cycle of photosynthesis is RuBP (ribulose-1,5-bisphosphate). During this cycle, the enzyme ribulose bisphosphate carboxylase (RuBisCO) catalyzes the addition of a CO₂ to ribulose bisphosphate (RuBP), producing 3-phosphoglycerate (3-PGA). This is then converted into glyceraldehyde 3-phosphate (G3P) using ATP and NADPH. Some of the G3P molecules are used to build glucose, while the remaining G3P molecules are used to regenerate RuBP, allowing the process to continue.
For every three 'turns' of the Calvin cycle, six G3P are generated - one of these is exported from the cycle, and the remaining five are used to regenerate three RuBP molecules with the help of ATP. Therefore, the compound produced during the regeneration step is RuBP, which is ready for more CO₂ fixation in the next cycle round.
