The enzymatic release of energy from organic compounds (especially carbohydrates and fats) which requires oxygen as the terminal electron acceptor. The oxidation of nitrite (NO2) to nitrate (NO3), using oxygen (O2) as the electron acceptor. Nitrite oxidation is the final step in nitrification, the oxidation of ammonia to nitrate, and nitrite oxidoreductase (NOR) is the key enzyme complex that catalyzes the conversion of nitrite to nitrate in nitrite oxidizing species. The enzymatic release of energy from organic compounds (especially carbohydrates and fats) which either requires oxygen (aerobic respiration) or does not (anaerobic respiration). A nearly universal metabolic pathway in which the acetyl group of acetyl coenzyme A is effectively oxidized to two CO2 and four pairs of electrons are transferred to coenzymes. The acetyl group combines with oxaloacetate to form citrate, which undergoes successive transformations to isocitrate, 2-oxoglutarate, succinyl-CoA, succinate, fumarate, malate, and oxaloacetate again, thus completing the cycle. In eukaryotes the tricarboxylic acid is confined to the mitochondria. See also glyoxylate cycle. A process whereby a series of electron carriers operate together to transfer electrons from donors such as NADH and FADH2 to oxygen to generate a transmembrane electrochemical gradient. The oxidation of arsenite to arsenate, using oxygen (O2) as the electron acceptor. Arsenite oxidase provides electrons to an electron carrier which transfers them to oxygen utilizing respiratory systems. The metabolic process by which ammonia (NH3) is oxidized to nitrite (NO2) in the presence of oxygen; enzymatic reactions convert ammonia to hydrazine, and hydrazine to nitrite. null The metabolic process by which carbon monoxide (CO) is oxidized to carbon dioxide (CO2) to generate energy. Conservation of energy in this process likely uses sodium ion gradients for ATP synthesis and is coupled to quantitative sulfide methylation. The oxidation of hydrogen (H2) to water (H2O), using oxygen (O2) as the electron acceptor. A hydrogenase enzyme binds H2 and the hydrogen atoms are passed through an electron transfer chain to O2 to form water. The chemical reactions and pathways by which a cell derives energy from organic compounds; results in the oxidation of the compounds from which energy is released. The metabolic process by which ferrous ions (Fe2+) are oxidized to ferric ions (Fe3+) to generate energy, coupled to the reduction of carbon dioxide.
