Question

Why does photorespiration increase with temperature?

Solution

Photorespiration:

  1. Photorespiration happens when the CO2 levels inside a leaf become low.
  2. This occurs on hot dry days when a plant is compelled to close its stomata to forestall the overabundance of water.
  3. Assuming that the plant keeps on endeavoring to fix CO2 when its stomata are shut, the CO2 will get spent and the O2 proportion in the leaf will build comparative with CO2 concentrations.
  4. When the CO2 levels inside the leaf drop to around 50 ppm, Rubisco begins to join O2 with RuBP rather than CO2.
  5. The net consequence of this is that as opposed to delivering 2 3-C PGA particles, just a single molecule of PGA is created and a harmful 2C atom called phosphoglycolate is expelled.
