Is photorespiration present at low co2 concentration in c3 and c4 plants?
Asked by arushidabhade | 18th Jan, 2020, 10:56: PM
Expert Answer:
- Photorespiration occurs when the concentration of CO2 is low in C3 and C4 plants.
- It is a wasteful metabolic pathway which occurs when rubisco, the carbon-fixing enzyme of the Calvin cycle, grabs O2 rather than CO2 in the absence of plenty of CO2.
- It uses up fixed carbon, wastes energy, and tends to happens when plants close their stomata (leaf pores) to reduce water loss.
- High temperatures make it even worse.
