During carbon fixation (Phase 1 of the Calvin cycle), carbon dioxide (CO2) is attached to ribulose bisphosphate (RuBP) by the enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase, commonly known as RuBisCO. This reaction produces an unstable intermediate that quickly breaks down into two molecules of 3-phosphoglycerate (3-PGA).
during carbon fixation (phase1), co2 is attached to RuBP by the enzyme?
