Does photorespiration help avoid photorespiration?

  1. Oct 19, 2013 #1
    In C3 plants, RuBisCO acts as an oxygenase when CO2 concentration is below a certain value. As a result, a process called photorespiration takes place.
    Photorespiration leads to the formation of toxic ammonia and CO2. Moreover, it uses up ATP and don't form glucose. So its considered a wasteful process.

    I was wondering if the formation of CO2 helps to increase its concentration and thereby result in RuBisCO acting as a carboxylase (which is what we want). So in a way, can we say that photorespiration stops itself from proceeding?
