Why is RuBisCO the most abundant enzyme in the world?

Why is RuBisCO the most abundant enzyme in the world?
  1. It has a much greater affinity for O₂ than CO₂
  2. It has a much greater affinity for CO₂ when the CO₂:O₂ is nearly equal
  3. It is the only enzyme that can catalyse the reaction between RuBP and CO₂
  4. It has a much greater affinity for CO₂ than O₂

Solution

RuBisCO is the most abundant enzyme in the world because it has a much greater affinity for CO₂ when the CO₂:O₂ is nearly equal, which is the characteristic that makes it so abundant.
