What determines which of the two (CO₂ or O₂) will bind to RuBisCO?

What determines which of the two (CO₂ or O₂) will bind to RuBisCO?
  1. The affinity of RuBisCO for CO₂
  2. The biological function of photorespiration
  3. The relative concentration of O₂ and CO₂
  4. The productivity and yields of C₄ plants

Solution

The relative concentration of O₂ and CO₂ determines which of the two will bind to RuBisCO, as the binding is competitive.
