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 chemical reactions and pathways by which a cell derives energy from inorganic compounds; results in the oxidation of the compounds from which energy is released. 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. The chemical reactions and pathways resulting in the formation of precursor metabolites, substances from which energy is derived, and any process involved in the liberation of energy from these substances. The chemical reactions and pathways resulting in the formation of methane, a colorless, odorless, flammable gas with the formula CH4. It is the simplest of the alkanes. The oxidation of ammonium (NH4) to nitrogen (N2) in the absence of oxygen, using nitrite (NO2) as the electron acceptor. It is suggested that hydroxylamine and ammonium are combined to yield hydrazine, which is subsequently oxidized to N2. The chemical reactions and pathways resulting in the conversion of lead sulfide to lead sulfate. 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. 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 chemical reactions and pathways by which individual cells transform chemical substances. 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 metabolic process by which ferrous ions (Fe2+) are oxidized to ferric ions (Fe3+) to generate energy, coupled to the reduction of carbon dioxide.
