Oxidation of carbohydrates in plants with the release of carbon dioxide during photosynthesis.

photorespiration

(ˌfəʊtəʊˌrɛspəˈreɪʃən)
n
(Botany) (in plants) a reaction that occurs during photosynthesis in which oxygen is assimilated and used to oxidize carbohydrates, with the release of carbon dioxide: differs from normal respiration in that there is no production of energy in the form of ATP

We designed a hydrogen producing bioreactor where the novel photorespiration will enable to utilize the organic material of the cell as an electron source for H2 production.
2] concentration, the increase in temperature modifies the kinetic constants of rubisco, and increases oxygenation rate preferably to carboxylation, consequently increases photorespiration and decreases net photosynthesis.
In some models, it is the indirect effect of temperature on stomatal conductance that causes the highest decline in photosynthesis (Doughty & Goulden, 2008; Lloyd & Farquhar, 2008), but others showed that direct effects on photorespiration and photosynthetic machinery are more important (Galbraith et al.
In the present study, the mid-season decline in midday NEE we observed may be attributed to a decline in GEE (values closer to zero) associated with high midday temperatures and water limitation leading to stomatal closure and high rates of photorespiration in this plant community dominated by the [C.
