Plastids and mitochondria need to be spatially close as some metabolic pathways like photorespiration require the association of both organelles to recycle glycolate and detoxify the ammonium produced during photorespiration.

However, at higher temperatures and lower CO 2 concentrations, RuBisCO adds oxygen instead of carbon dioxide, to form the unusable product glycolate in a process called photorespiration.

They are unable to grow if all three pathways are knocked out, despite having a carbon concentrating mechanism that should dramatically reduce the rate of photorespiration ( see below ).
35.
Their lights are designed for horticultural purposes and are not only lit throughout the growing period of a crop, but can also effectively control the crop's photorespiration and photosynthesis.

The salvaging pathway for the products of RuBisCO oxygenase activity is more commonly known as photorespiration, since it is characterized by light-dependent oxygen consumption and the release of carbon dioxide.
37.
The following day, they close their stomata and release the carbon dioxide fixed the previous night into the presence of RuBisCO . This saturates RuBisCO with carbon dioxide, allowing minimal photorespiration.
38.
While it is common to refer to the entire process as photorespiration, technically the term refers only to the metabolic network which acts to rescue the products of the oxygenation reaction ( phosphoglycolate ).
39.
Although the functions of photorespiration remain controversial, it is widely accepted that this pathway influences a wide range of processes from bioenergetics, photosystem II function, and carbon metabolism to nitrogen assimilation and respiration.

Peroxisomes in plant cells are involved in photorespiration ( the use of oxygen and production of carbon dioxide ) and symbiotic nitrogen fixation ( the breaking apart of diatomic nitrogen ( N 2 ) to reactive nitrogen atoms ).
