Using ¹⁴CO₂ as a radioactive tracer,which molecule would be the last to incorporate ¹⁴C within the Calvin cycle? A)ribulose biphosphate (RuBP) B)glyceraldehyde-3-phosphate (G3P) C)rubisco D)1,3-biphosphoglycerate (1,3-BPG) E)3-phosphoglycerate (3PG)

Question

Quizplus · Accepted Answer

Ribulose biphosphate (RuBP) is the molecule that initially reacts with CO2, so it would be the last to incorporate the radioactive carbon as it is regenerated at the end of the Calvin cycle.
