WebApr 12, 2024 · When roots are supplying abundant amount of nutrients to the shoots and leaves, there is a higher leaf nitrogen content and more activity of the RuBisCo enzymes that enable photosynthesis to occur [3,11,30,31]. Leaves that are more active photosynthetically can supply more photosynthate to the roots and the microbes in the … RuBisCO is important biologically because it catalyzes the primary chemical reaction by which inorganic carbon enters the biosphere. While many autotrophic bacteria and archaea fix carbon via the reductive acetyl CoA pathway, the 3-hydroxypropionate cycle, or the reverse Krebs cycle, these pathways are relatively small contributors to global carbon fixation compared to that catalyzed by RuBisCO. Phosphoenolpyruvate carboxylase, unlike RuBisCO, only temporarily fixes carbon. R… conecuh county alabama zip codes https://shinestoreofficial.com
