Question

Why is photorespiration bad for C3 plants?

Answer 1

Photorespiration:

1. Photorespiration is the process of taking in molecular oxygen (O₂) and releasing carbon dioxide (CO₂) from organic substances in response to light.
2. Photorespiration is harmful to C3 plants because it reduces plant productivity, which is why it is also known as a wasteful process.
3. Many higher plants use photorespiration as a means of respiration.
4. The oxidative photosynthetic, commonly known as C2 photosynthesis or the carbon cycle, is a type of photosynthetic process.
5. RuBisCO reacts with oxygen in this phase, competing with the Calvin cycle.
