Fluxes and Energetics of Photosynthesis and Photorespiration
Fluxes and Energetics of Photosynthesis and Photorespiration
This Demonstration shows the fluxes and partitioning of energy associated with primary carbon metabolism. The upper-left graph shows the flux of leaf-level net carbon assimilation (; ), and the three components that contribute to : the fluxes of photosynthetic carbon uptake (; ), photorespiratory carbon loss (; ) and mitochondrial carbon loss (; ). The three pie charts show the energy partitioned between photosynthesis () and photorespiration () specifically for the partitioning of electrons (top right), of (bottom left) and of (bottom right).
