In anaerobic environments, organisms rely on alternative electron acceptors to sustain respiration. The molecule’s ability to accept electrons cleanly—forming water as a byproduct—makes it an ideal terminal electron acceptor.
Oxygen as an Electron Acceptor in Industrial Corrosion Control
Biological Significance and Efficiency The utilization of oxygen as an electron acceptor grants organisms a significant metabolic advantage. The acceptance of these electrons enables the establishment of a proton gradient that drives the synthesis of adenosine triphosphate (ATP), the universal currency of cellular energy.
Although these pathways generate less energy than aerobic respiration, they allow microbial life to thrive in oxygen-depleted habitats such as deep sediments, the guts of animals, and hydrothermal vents. In wastewater treatment, the oxygen demand of microbial communities is a critical parameter for managing organic pollution.
