Photorespiration is the alternate pathway for production of glyceraldehyde 3-phosphate (G3P) by RuBisCO, ...
Photorespiration is an alternate pathway for rubisco, the main enzyme of photosynthesis (specifically, the Calvin cycle). Although rubisco favors carbon, it can also use oxygen, producing glycolate .
Photorespiration and C4 Plants
All plants carry on photosynthesis by ...
photorespiration
[Gk. photos, light + L. respirare, to breathe]
A metabolic pathway that consumes oxygen, releases carbon dioxide, generates no ATP, and decreases photosynthetic output; generally occurs on hot, dry, bright days, ...
Photorespiration
Stomata and CO2 Concentration
Stomata (singular stoma) are microscopic openings on the undersurface of leaves that allow gas exchange and water evaporation from inside the leaf.
Photorespiration The conversion of organic carbon into carbon dioxide without the production of energy-rich metabolites; ...
photorespiration is minimal in C4 plants compared to C3 plants.

photorespiration In C3 plants, respiration rates increase
photosynthesis The biochemical process by which green plants and some bacteria capture light energy and use it to produce chemical bonds.
The product of that reaction forms glycolic acid, a chemical that can be broken down by photorespiration, producing neither NADH nor ATP, in effect dismantling the Calvin Cycle.
In plant cells, peroxisomes play a variety of roles including converting fatty acids to sugar and assisting chloroplasts in photorespiration. In animal cells, peroxisomes protect the cell from its own production of toxic hydrogen peroxide.
