Answer to Question #217115 in Cell Biology for Vibha

Question

1) Which enzyme is responsible for the absorption of CO2 from the air, in plants....?

2) What is the work of Rubisco enzyme...?

Answer 1

1) An enzyme called RuBisCO (Ribulose-1,5-bisphosphate carboxylase-oxygenase) helps catalyze the reaction that turns CO₂ into glucose, which plants use as an energy source.

2) Ribulose-1,5-bisphosphate carboxylase-oxygenase catalyzes the addition of gaseous carbon dioxide to ribulose-1,5-bisphosphate (RuBP), generating two molecules of 3-phosphoglyceric acid (3-PGA), and is thus the key enzyme in CO₂ assimilation.
