Question

Why does photorespiration increase with temperature?

Answer 1

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.
