Who observed the process of photorespiration

1.	Who observed the process of photorespiration
Answer» In the 1920s, the German biochemist\xa0Otto Warburg\xa0(1883-1970) discovered that plants consumed oxygen at a higher rate when they were illuminated. He also found that this increased rate of oxygen consumption inhibited photosynthesis. Stimulation of oxygen consumption by light is now referred to as photorespiration.\xa0Photorespiration\xa0(also known as the oxidative photosynthetic carbon cycle, or C2\xa0photosynthesis) refers to a\xa0process\xa0in plant metabolism where the enzyme RuBisCO oxygenates RuBP, wasting some of the energy produced by photosynthesis. ...\xa0Photorespiration\xa0also incurs a direct cost of one ATP and one NAD(P)H.
