Detailed explanation-1: -Triose phosphate is recycled to regenerate RuBP. For the Calvin cycle to run continuously, it is important to regenerate the carbon accepting molecule RuBP. The regeneration step requires one ATP for phosphorylation to create one RuBP per cycle or per carbon dioxide fixed.

Detailed explanation-2: -In the last stage of the Calvin Cycle, RuBP is regenerated, which enables the system to prepare for more CO2 to be fixed.

Detailed explanation-3: -The Calvin cycle has three stages. In stage 1, the enzyme RuBisCO incorporates carbon dioxide into an organic molecule. In stage 2, the organic molecule is reduced. In stage 3, RuBP, the molecule that starts the cycle, is regenerated so that the cycle can continue.

Detailed explanation-4: -One exits the cycle and is used to make glucose, while the other five must be recycled to regenerate three molecules of the RuBP acceptor.

Detailed explanation-5: -RuBP, which stands for ribulose bisphosphate, is a 5-carbon molecule that is involved in the Calvin cycle, which is one of the photosynthesis’s light-independent processes. With the aid of an enzyme called RuBisCO, atmospheric carbon dioxide is coupled with RuBP to generate a 6 carbon molecule.
