The Chemistry of Molecular Oxygen Metabolism can be eitheraerobic(requiring oxygen) oranaerobic(occurring in the absence of oxygen). Anaerobic metabolism is the older process: Earth's atmosphere has contained molecular oxygen for less than half the planet's existence. For organisms like yeast that...

Organic matter (OM) attachment to mineral surfaces is dynamic, sensitive to interfacial energies and topology, and exhibits features reminiscent of a partial wetting phenomenon. Mineral-derived reactive oxygen species represent overlooked but undeniably key reactants in the oxidation and transformation of...
