The 12 pages that link to Photorespiration, each with the reason it gives.

• PhotosynthesisCompared with: It competes with carbon fixation, especially when leaves are hot or water-stressed.

• ChloroplastRelated: It occurs in chloroplast-centered metabolism and can reduce photosynthetic efficiency.

• C4 carbon fixationRelated: Reducing this wasteful reaction is the main advantage of C4 carbon concentration.

• Calvin cycleCompared with: It exposes a costly side reaction that competes with the cycle’s productive carbon-fixation route.

• Crassulacean acid metabolismRelated: Concentrating carbon dioxide around Rubisco can limit this wasteful reaction.

• CAM photosynthesisRelated: CAM’s internal carbon dioxide supply can limit Rubisco’s oxygen reaction in daylight.

• C3 carbon fixationRelated: It diverts Rubisco activity from carbon fixation and consumes energy.

• RuBisCORelated: It results from RuBisCO’s competing oxygenase activity.

• Biological carbon fixationRelated: It wastes energy and releases previously fixed carbon, limiting photosynthetic productivity.

• Glyoxylic acidRelated: Photorespiratory metabolism produces glyoxylate from glycolate.

• Mesophyll cellsRelated: It can reduce carbon fixation in mesophyll, especially when heat and drought limit carbon dioxide supply.

• Plant metabolismCompared with: It competes with productive carbon fixation and illustrates a cost of photosynthetic chemistry.
