– O2 competes with CO2 for rubisco’s active site – rubisco catalyzes two reactions: 1) addition of carbon to RuBP; forms 2 PGA molecules (photosynthesis) 2) addition of oxygen to RuBP; forms 1 PGA and one glycolate (photorespiration) – photorespiration decreases the production of carbohydrates by removing PGA from the Calvin cycle – glycolate is…
