Definitions for "Photorespiration"
The removal of O from the atmosphere by Rubisco and the subsequent biochemical reactions that serve to recycle some of the reduced carbon.
The energetically-wasteful substitution of oxygen for carbon dioxide in the dark reactions of photosynthesis, which occurs when plant stomata close and carbon dioxide concentration declines.
a process in which CO2 is released without the production of ATP or NADPH; acts to undo the work of photosynthesis.
Enhanced respiration of plants in the light relative to dark respiration.
