Question

photorespiration

Accepted Answer

O2 competitively inhibits RuBisCO, so forms phosphoglycolate instead of GP only when [CO2] low, its toxic so converted into other organic molecules using ATP, reduces efficiency of photosynthesis, happens as more O2 present and less CO2 due to closing of stoma
