What is Photorespiration?

What is Photorespiration?
  1. A process in C₃ plants where RuBP binds with CO₂ to form 2 molecules of 3PGA
  2. A process in C₃ plants where RuBP binds with O₂ instead of CO₂
  3. A process in C₄ plants where C₄ acid is broken down to release CO₂
  4. A process that occurs in both C₃ and C₄ plants

Solution

Photorespiration is a process that occurs in C₃ plants where RuBP binds with O₂ instead of CO₂, leading to the formation of one molecule of phosphoglycerate and phosphoglycolate and the release of CO₂.
