  2. Biological carbon fixation - Wikipedia

    en.wikipedia.org/wiki/Biological_carbon_fixation

    Cyanobacteria such as these carry out photosynthesis.Their emergence foreshadowed the evolution of many photosynthetic plants and oxygenated Earth's atmosphere.. Biological carbon fixation, or сarbon assimilation, is the process by which living organisms convert inorganic carbon (particularly carbon dioxide, CO 2) to organic compounds.

  3. Carbaminohemoglobin - Wikipedia

    en.wikipedia.org/wiki/Carbaminohemoglobin

    Transporting Carbon Dioxide: This process allows for the transport of carbon dioxide from the tissues to the lungs. It is essential for maintaining the balance of gases in the bloodstream and to guarantee the removal of waste carbon dioxide from the body. [17] Buffering Blood pH: The binding of carbon dioxide to hemoglobin helps buffer blood pH.

  4. Bicarbonate buffer system - Wikipedia

    en.wikipedia.org/wiki/Bicarbonate_buffer_system

    k H CO 2 is a constant including the solubility of carbon dioxide in blood. k H CO 2 is approximately 0.03 (mmol/L)/mmHg; p CO 2 is the partial pressure of carbon dioxide in the blood; Combining these equations results in the following equation relating the pH of blood to the concentration of bicarbonate and the partial pressure of carbon ...

  5. Hydrogenotroph - Wikipedia

    en.wikipedia.org/wiki/Hydrogenotroph

    [citation needed] Experimentation has revealed that hydrogenotrophic bacteria can convert carbon dioxide into food more rapidly than plants, making them an efficient and sustainable alternative to implement into plant-based high-protein diets and as a substitute in products that use plant extracts and oils. [5]

  6. Carbonic acid - Wikipedia

    en.wikipedia.org/wiki/Carbonic_acid

    Hence the majority of carbon dioxide at geophysical or biological air-water interfaces does not convert to carbonic acid, remaining dissolved CO 2 gas. However, the uncatalyzed equilibrium is reached quite slowly: the rate constants are 0.039 s −1 for hydration and 23 s −1 for dehydration.

  7. Chemosynthesis - Wikipedia

    en.wikipedia.org/wiki/Chemosynthesis

    Venenivibrio stagnispumantis gains energy by oxidizing hydrogen gas.. In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic compounds (e.g., hydrogen gas, hydrogen sulfide) or ferrous ions as a source of energy, rather than sunlight, as in ...

  8. Chloride shift - Wikipedia

    en.wikipedia.org/wiki/Chloride_shift

    The subsequent decrease in intracellular bicarbonate concentration reverses chloride-bicarbonate exchange: bicarbonate moves into the cell in exchange for chloride moving out. Inward movement of bicarbonate via the Band 3 exchanger allows carbonic anhydrase to convert it to CO 2 for expiration. [3]

  9. Cellular respiration - Wikipedia

    en.wikipedia.org/wiki/Cellular_respiration

    From the complete oxidation of one glucose molecule to carbon dioxide and oxidation of all the reduced coenzymes. Although there is a theoretical yield of 38 ATP molecules per glucose during cellular respiration, such conditions are generally not realized because of losses such as the cost of moving pyruvate (from glycolysis), phosphate, and ...
