KnowraC3 carbon fixationLinked fromLinked fromThe 13 pages that link to C3 carbon fixation, each with the reason it gives.All 13Broader topic 5Related 4Narrower topic 1Compared with 3PhotosynthesisBroader topic: It is the predominant pathway in plants and a target for improving crop productivity.ChloroplastRelated: Most plant chloroplasts use this pathway, whose efficiency falls when photorespiration increases.C4 carbon fixationCompared with: Unlike C4 plants, C3 plants lack a preliminary carbon-concentrating cycle.StomataRelated: Stomatal carbon dioxide supply limits this pathway, especially during drought.PoaceaeRelated: Many grasses use this pathway, while other grass lineages evolved C4 photosynthesis.Crassulacean acid metabolismNarrower topic: CAM modifies this pathway by supplying the Calvin cycle with carbon dioxide stored overnight.CAM photosynthesisCompared with: Unlike CAM, C3 plants generally take up carbon dioxide during daylight.PhotorespirationBroader topic: Photorespiration is especially consequential in plants relying on this mode of carbon fixation.PineappleCompared with: Most familiar fruit crops use C3 photosynthesis, while pineapple relies on CAM.Melvin CalvinBroader topic: Calvin’s pathway describes the core carbon-fixation reactions in C3 plants.Mesophyll cellsRelated: Most mesophyll cells fix carbon through this pathway, which is vulnerable to photorespiration.Plant metabolismBroader topic: It is the dominant route in plants and a major target for improving photosynthetic efficiency.Plant Physiological PhenomenaBroader topic: It is the predominant pathway, but its performance declines when photorespiration is substantial.
