Carbon Cycle In subject area: Biochemistry, Genetics and Molecular Biology The carbon cycle refers to the circulation of carbon back and forth between living forms and the environment via various biogeochemical cycles (Figure I).

a. volcanic eruptions. b. rain. The biological carbon cycle Biology plays an important role in the movement of carbon between land, ocean, and atmosphere through the processes of photosynthesis and respiration. Virtually all multicellular life on Earth depends on the production of sugars from sunl...
Carbon Cycle Carbon is the fourth most abundant element in the Universe, after the elements hydrogen, helium, and oxygen. As for the Earth’s crust, carbon is the 15th most abundant element. Thus, carbon is widely circulated and converted from one form to another. Carbon cycle is one of ...
Efforts to produce aromatic monomers through catalytic lignin depolymerization have historically focused on aryl–ether bond cleavage. A large fraction of aromatic monomers in lignin, however, are linked by various carbon–carbon (C–C) bonds that are mo

While this flux is small relative to the gross fluxes of carbon in the global carbon cycle, it is significant relative to the net fluxes to and from the atmosphere (Fig. 1; Regnier et al., 2022), and Earth system models currently do not simulate this lateral carbon transfer. However, ...
Diagram of global carbon cycling in ecosystems mediated by soil microorganisms. The yellow bow-ties represent microbial respiration/catalysis of carbon. Arrows represent fluxes among pools. Pathway A represents that partially decomposed plant-derived carbon contributes the formation of soil stable carbon po...
Conceptual diagram of ice sheets in the global carbon cycle. The diagram indicates the potential direct and indirect impacts of ice sheets. (1) direct sequestration or emission of CO2/CH4 by microbial activity in ice sheets, (2) burial of terrestrial OM exported from ice sheets by rivers, (...
Soil microorganisms are central to sustain soil functions and services, like carbon and nutrient cycling. Currently, we only have a limited understanding of the spatial-temporal dynamics of soil microorganisms, restricting our ability to assess long-term
