High photorespiration

WebPhotorespiration is the oxygenation of RuBP by RUBISCO followed by photorespiratory glycolate metabolism. Competition between O2 and CO 2 reduces the rate of carbon … WebPhotorespiration is a wasteful respiratory process, which hinders the photosynthetic process in many higher plants. The reaction in which carbon dioxide and water combine to give carbohydrates is termed carbon fixation.

WebAug 10, 2024 · High photosynthetic capacity and, therefore, high biomass productivity of C4 plants as compared with C3 plants can be attributed to the CO 2-concentrating mechanism (CCM) in BS chloroplasts. At temperatures of 20–30 °C, Rubisco in C4 plants encounters almost saturated CO 2 concentrations, thus photorespiration is very low [ 50 ]. WebJan 22, 2024 · C4 photosynthesis is an evolutionary adaptation that minimizes the adverse effects of the high photorespiration rate. Although it is widely accepted that the C4 plants are evolved from C3 ancestors, the knowledge about the details of this process is yet to be complete.
