  • Rubisco in pop science

3 Carbon Fixation

  • Turning carbon from the air into carbohydrates
  • Combines carbon from \(CO_2\), light, and water to get carbohydrates
    • \(6CO_2 + 6H_2O + light = \text{carbs}\) # Faults
  • Rubisco sometimes accidentally binds oxygen to a sugar chain in a process called photorespiration
    • The cell actually has to expend more energy to fix this mistake
  • Also it's like really really slow, processing around 3 reactions per second instead of other enzymes which often process thousands
