Topic hierarchy

5.10A: The Energetics of Chemolithotrophy
Chemolithotrophs use electron donors oxidized in the cell, and channel electrons into respiratory chains, producing ATP.
5.10B: Hydrogen Oxidation
While there are several mechanisms of anaerobic hydrogen oxidation, organisms can also use hydrogen as an energy source aerobically.
5.10C: Oxidation of Reduced Sulfur Compounds
Sulfur oxidation involves the oxidation of reduced sulfur compounds, inorganic sulfur, and thiosulfate to form sulfuric acid.
5.10D: Iron Oxidation
Ferric iron is an anaerobic terminal electron acceptor, with the final enzyme a ferric iron reductase.
5.10E: Nitrification
Nitrification is the process by which ammonia (NH₃) or ammonium (NH₄⁺) is converted to nitrite (NO₂⁻) and then nitrate (NO₂⁻) by bacteria.
5.10F: Anammox
Anammox, an abbreviation for ANaerobic AMMonium OXidation, is a globally significant microbial process of the nitrogen cycle.
5.10G: Benzoate Catabolism
5.10H: Polycyclic Aromatic Hydrocarbons
Polycyclic aromatic hydrocarbons are potent atmospheric pollutants that consist of fused aromatic rings and do not contain heteroatoms.
