13.7: Photorespiration and Photosynthetic Pathways

WebPhotorespiration is the process of light-dependent uptake of molecular oxygen (O 2) concomitant with release of carbon dioxide (CO 2) from organic compounds. The gas exchange resembles respiration and is the reverse of photosynthesis where CO 2 is fixed and O 2 released. What is photorespiration and what is its effect? WebMay 4, 2024 · Photorespiration As its name suggests, ribulose-1,5-bisphosphate carboxylase/oxygenase ( RuBisCO) catalyzes two different reactions. The first is adding CO 2 to ribulose-1,5- bisphosphate (RuBP) — the carboxylase activity. The second is adding O 2 to RuBP — the oxygenase activity. how do you measure wheelbase https://natureconnectionsglos.org

WebC1 metabolism in plants is known to be involved in photorespiration, nitrogen and amino acid metabolism, as well as methylation and biosynthesis of metabolites and biopolymers. Although the flux of carbon through the C1 pathway is thought to be large, its intermediates are difficult to measure and relatively little is known about this potentially ubiquitous … WebMar 26, 2024 · During the process of photorespiration carbon dioxide is released and also energy is utilized. So we can say photorespiration wastes energy and decreases the synthesis of sugar as it releases carbon dioxide utilized for the sugar production. It is also known as the C$_2$cycle. It is initiated in chloroplast but it occurs in peroxisomes.
