The enzyme RuBisCO catalyses the joining of CO₂ to which molecule?
Aglucose, the final product
BG3P (glyceraldehyde-3-phosphate)
CRuBP, a 5-carbon sugar
DATP, the energy currency
Answer & Solution
Correct answer: C. RuBP, a 5-carbon sugar
RuBisCO catalyses the carboxylation of RuBP: CO₂ + RuBP
→ unstable 6-carbon → 2 × 3-PGA.
The first stable step of carbon fixation in C3 plants.
G3P is the downstream reduction product
glucose is the eventual exit product
ATP is energy currency.
