Why do we need a more rigorous use of the term C sequestration?
May 29, 2023 · In biochemistry, sequestration is one means of reversibly inhibiting enzymes which depend on divalent metal cations (such as magnesium) for their activity. Such agents are used, for example, to help preserve blood for storage and subsequent use in transfusion.

: to bind (a metal or metal ion) in the form of a soluble complex or chelate by adding a suitable reagent for the purpose of preventing precipitation in water solution by chemical agents that would normally bring it about, of solubilizing precipitates already formed, or of otherwise suppressing undesired chemical or biological activity.
Oct 1, 2010 · Photosynthetic assimilation of atmospheric carbon dioxide by land plants offers the underpinnings for terrestrial carbon (C) sequestration. A proportion of the C captured in plant biomass is partitioned to roots, where it enters the pools of soil organic C and soil inorganic C and can be sequestered for millennia.

May 30, 2024 · In the global carbon cycle, atmospheric carbon emissions, both ‘natural’ and anthropogenic, are balanced by carbon uptake (i.e., sequestration) that mostly occurs via photosynthesis, plus a much smaller proportion via geological processes.

The dissonance in terms of properties between small molecular assemblies with definite stoichiometries and mesoscale assemblies of heterogeneous size, molecular mass, composition, and presumably stochastic stoichiometry prompts a reassessment of basic organizational principles in cells. Despite this stochasticity, mesoscale assemblies output highly...
Recent studies have begun to shed light on the significance of condensates for enhancing enzymatic reactions in plants, which could be achieved through one of the three major mechanisms or their combinations (summarized in Box 2C). In most algae and hornworts, the CO2-assimilating enzyme Rubisco condenses within a chloroplast organelle called the p...
We summarize some outstanding questions in Box 3. To further explore and utilize condensates as catalysts of biochemical reactions in plants, we should prioritize the non-invasive measurements of reaction rates in the dense versus the dilute phases in living cells. In the same context, the composition of condensates, their internal organization, th...

Oct 31, 2023 · Carbon sequestration is the removal of C from the atmosphere and the storage, for example, in soil. It has the potential to partially compensate for anthropogenic greenhouse gas emissions and is, therefore, an important piece in the global climate change mitigation puzzle.
