Question

Quizplus · Accepted Answer

Rubisco catalyzes the first major step of carbon fixation in the Calvin cycle, where it attaches a molecule of carbon dioxide (a 1-carbon molecule) to ribulose-1,5-bisphosphate (RuBP, a 5-carbon molecule), forming a 6-carbon intermediate that immediately splits into two 3-carbon molecules of 3-phosphoglycerate.
