An electrochemical CO 2 electrolyzer that operates at room temperature has not yet been commercialized. Elevated temperature solid oxide electrolyzer cells (SOECs) for CO 2 reduction to CO are commercially available. For example, Haldor Topsoe offers SOECs for CO 2 reduction with a reported 6–8 kWh per Nm 3 [note 1] CO produced and purity up ...
During respiration the C-H bonds are broken by oxidation-reduction reaction and so carbon dioxide and water are also produced. The cellular energy-yielding process is called cellular respiration. Classifications of respiration
Aerobic respiration requires oxygen (O 2) in order to create ATP.Although carbohydrates, fats and proteins are consumed as reactants, aerobic respiration is the preferred method of pyruvate production in glycolysis, and requires pyruvate be transported the mitochondria in order to be oxidized by the citric acid cycle.
Anaerobic cellular respiration and fermentation generate ATP in very different ways, and the terms should not be treated as synonyms. Cellular respiration (both aerobic and anaerobic) uses highly reduced chemical compounds such as NADH and FADH 2 (for example produced during glycolysis and the citric acid cycle) to establish an electrochemical gradient (often a proton gradient) across a membrane.
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 ...
This process generally produces CO 2, water and a collection of simple nutrients like nitrate or phosphate that can then be taken up by other organisms. The above general form, when considering O 2 as the oxidant, is the equation for respiration.

The brainstem respiratory centers decrease alveolar ventilation (hypoventilation) to create a rise in arterial carbon dioxide (CO 2) tension, resulting in a decrease of plasma pH. [1] However, as there is limitation for decreasing respiration, respiratory compensation is less efficient at compensating for metabolic alkalosis than for acidosis.
