The chemical reactions and pathways involving various organic and inorganic nitrogenous compounds; includes nitrogen fixation, nitrification, denitrification, assimilatory/dissimilatory nitrate reduction and the interconversion of nitrogenous organic matter and ammonium. The chemical reactions and pathways involving various organic and inorganic nitrogenous compounds, as carried out by individual cells. The enzymatic release of energy from organic compounds (especially carbohydrates and fats) which either requires oxygen (aerobic respiration) or does not (anaerobic respiration). 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 chemical reactions and pathways involving small molecules, any monomeric molecule of small relative molecular mass. The chemical reactions and pathways by which ammonia or ammonium is converted to molecular nitrogen or another nitrogen compound, with accompanying loss of electrons. 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 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 enzymatic release of energy from organic compounds (especially carbohydrates and fats) which uses compounds other than oxygen (e.g. nitrate, sulfate) as the terminal electron acceptor. The chemical reactions and pathways by which individual cells transform chemical substances.
