Most Triose Phosphate Is Recycled to Regenerate RuBP, Not Turned Into Products

The Calvin cycle can only keep running if the plant remakes its carbon dioxide acceptor.
That acceptor is ribulose bisphosphate (RuBP), a five-carbon molecule.
Most of the triose phosphate (TP) made in the cycle is used to rebuild RuBP, using energy from ATP.

Note

Regenerating RuBP keeps a supply of acceptor molecules ready for the next carbon dioxide.
Without this step the cycle would run out of RuBP and stop.

The 6-to-1 Split: Five Sixths of Triose Phosphate Goes Back Into the Cycle

Triose phosphate is the three-carbon sugar produced by the reduction stage of the Calvin cycle.
For every six molecules of triose phosphate made, the plant divides them two ways.
1. One molecule leaves the cycle to build carbohydrates and other products.
