WebApr 9, 2024 · In stage 3, RuBP, the molecule that starts the cycle, is regenerated so that the cycle can continue. Only one carbon dioxide molecule is incorporated at a time, so the cycle must be completed three times to produce a single three-carbon GA3P molecule, and six times to produce a six-carbon glucose molecule. Which of the following statements is true? WebOct 6, 2024 · Only 5 triose phosphate molecules are required for RuBP regeneration. The remaining 1 triose phosphate has 3 carbon atoms in it. Only 3 more carbon atoms are needed, which can be produced again in the next cycle. So, it would seem that, in total, only 2 cycles are needed to produce 1 glucose molecule.
