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.
