They capture energy locked within chemical bonds and convert it into a universal cellular currency, adenosine triphosphate. Ecological and Industrial Relevance The impact of bacterial respiration extends far beyond microscopic pond water.
Denitrification Sulfate Reduction Methanogenesis Pathways in Bacterial Anaerobic Respiration
In the absence of oxygen, however, many bacteria seamlessly switch to anaerobic pathways. Regulatory systems like the Arc two-component system allow the bacterium to sense oxygen levels and adjust gene expression accordingly.
Beneath the soil, within the human gut, and suspended in every aqueous environment, bacteria conduct a fundamental transaction with the universe. Comparative Efficiency Not all respiratory pathways yield the same energy output.
Denitrification Sulfate Reduction Methanogenesis Pathways in Bacterial Anaerobic Respiration
These include denitrification, which uses nitrate; sulfate reduction, which utilizes sulfate; and methanogenesis, which relies on carbon dioxide. For instance, lactic acid fermentation yields only 2 ATP per glucose.
