What happens in C₄ plants with respect to photorespiration?

What happens in C₄ plants with respect to photorespiration?
  1. Photorespiration occurs in C₄ plants
  2. Photorespiration does not occur in C₄ plants
  3. Photorespiration occurs at a higher rate in C₄ plants
  4. Photorespiration occurs in C₃ plants only

Solution

Photorespiration does not occur in C₄ plants because they have a mechanism that increases the concentration of CO₂ at the enzyme site, thereby ensuring that RuBisCO functions as a carboxylase and minimising the oxygenase activity.
