Activation of Rubisco regulates photosynthesis at high temperature and CO2.
T enzyme Rubisco, short for ribulose1,5-bisphosphate carboxylaseyoxygenase, is the enzyme that incorporates CO2 into plants during photosynthesis. As it constitutes about 30% of the total protein in a plant leaf, Rubisco is probably the most abundant protein on earth and a major sink for plant nitrogen. Rubisco is widely accepted as the ultimate rate-limiting step in photosynthetic carbon fixat...
متن کاملDimerization of CO2 at high pressure and temperature.
Understanding the behavior of simple molecular systems under the combined effect of high pressure (P) and temperature (T) has important implications in the modeling of planetary interiors, in the chemistry of detonation, and in the synthesis of new materials. Extreme conditions of P and T can be partially accessed in the laboratory either in heated diamond-anvil cells or in shock wave experimen...
متن کاملEffects of explicit atmospheric convection at high CO2.
The effect of clouds on climate remains the largest uncertainty in climate change predictions, due to the inability of global climate models (GCMs) to resolve essential small-scale cloud and convection processes. We compare preindustrial and quadrupled CO2 simulations between a conventional GCM in which convection is parameterized and a "superparameterized" model in which convection is explicit...
متن کاملCorrespondence: Reply to ‘Strongly-driven Re+CO2 redox reaction at high-pressure and high-temperature'
Santamaria-Perez et al.1 attempt to reproduce our CO2–SiO2 solid solution2. In their study1, mixtures of CO2 and SiO2 similar to those studied in our work2 were indirectly laser heated up to 2,400K and 50GPa by using Re as an internal heater, and a CO2–SiO2 solid solution was not obtained. Instead, the only temperature quenched crystalline phases identified by X-ray diffraction were: known poly...
متن کاملStable solid and aqueous H2CO3 from CO2 and H2O at high pressure and high temperature
Carbonic acid (H2CO3) forms in small amounts when CO2 dissolves in H2O, yet decomposes rapidly under ambient conditions of temperature and pressure. Despite its fleeting existence, H2CO3 plays an important role in the global carbon cycle and in biological carbonate-containing systems. The short lifetime in water and presumed low concentration under all terrestrial conditions has stifled study o...
