Abstract
Energy homeostasis is critical for cellular function. Significant increases in energy demand or reduced energy supply, however, often result in cellular dysfunction and death. Since mitochondria are the primary cellular energy source, their impairment is often pathogenic. Accordingly, quantitative measurements of cellular and mitochondrial energy utilization and production are crucial for understanding disease development and progression. In the final step of cellular respiration, specifically, oxidative phosphorylation within the mitochondria, oxygen is consumed and drives ATP production. Herein, we provide the complete protocols for measuring oxygen consumption rates and their coupling to ATP production in intact and permeabilized cells, as well as in mitochondria isolated from tissue using the Seahorse XF Extracellular Flux Analyzer (Agilent Technologies).
