Enhanced respiration of plants in the light relative to dark respiration
Found op http://life.bio.sunysb.edu/marinebio/glossary.opq.html
Increased respiration that occurs in photosynthetic cells in the light, due to the ability of RuDP carboxylase to react with oxygen as well as carbon dioxide. Reduces the photosynthetic efficiency of C3 plants.

(from the article `Life Sciences`) The rising level of CO2 was decreasing the rate of photorespiration in plants. Photorespiration is a process in which plants turn sugars produced ... ...become rate-limiting. At light saturation, rate increases with temperature until a point is reached beyond which...

photorespiration 1. The oxidation of carbohydrates in plants with the release of carbon dioxide during photosynthesis. 2. A process in which an organism takes in oxygen and releases carbon dioxide in the presence of light, occurring during photosynthesis in conditions in which there is a low concen...

Photorespiration, or "`photo-respiration`", is a process in plant metabolism by which RuBP (a sugar) has oxygen added to it by the enzyme (rubisco), instead of carbon dioxide during normal photosynthesis. This is the beginning step of the Calvin-Benson cycle. This process reduces efficiency of phot...
