- n. the light-dependent release of carbon dioxide and uptake of oxygen in photosynthetic organisms; an unavoidable side reaction of photosynthesis
Sorry, no etymologies found.
The net result is that photosynthesis becomes limited by the process of photorespiration.
Concentrating carbon dioxide in the bundle sheath cells minimizes photorespiration.
Many of these species, such as switchgrass and Miscanthus exhibit high yields because photorespiration is reduced.
As internal leaf CO2 concentrations decline due to stomatal closure, the enzyme Rubisco tends to fix more oxygen and liberates CO2 in a process known as photorespiration.
Substrates are formed by one of three processes: decomposition (hydrolytic breakdown of plant litter, oxidation, fermentation); N mineralization, and photosynthesis and photorespiration.
When the density of CO2 falls below the rubisco Km needed for fixing the CO2, the photosynthesis is slowed or stopped and the photorespiration increases.
This results in a process called “photorespiration” in which CO2 and energy are lost from the leaf.
1966-70 Continued microcosm studies: with Scott Nixon metabolism of brine microcosms and analog simulation showed rhodopsin photorespiration in pink Halophilic bacteria before it was found by physiologists.
There’s “photorespiration” which uses O2 and is wasteful but still used under some circumstances.
