Cellular energy production

Cellular energy production comprises the integrated pathways that extract energy from nutrients to generate ATP and reducing equivalents needed for cellular work. Core processes include glycolysis, which converts glucose to pyruvate and can produce ATP anaerobically; the citric acid (TCA) cycle, which oxidizes acetyl-CoA to CO2 while producing NADH, FADH2, and GTP/ATP; and oxidative phosphorylation, where electrons from NADH and FADH2 drive proton pumping across the inner mitochondrial membrane to generate a proton-motive force that powers ATP synthase to make ATP[6][5][8]. Cells also obtain energy from fatty acid β-oxidation and amino acid catabolism, with pathway usage regulated by hormones and cellular signaling to match energy demand[5]. ATP, NADH, and NADPH serve as activated carriers that distribute energy and reducing power for biosynthesis, transport, and mechanical work[4]. “Cellular energy production” is a physiological process, not a single molecular target, so therapeutic interventions typically act on specific enzymes, transporters, or complexes within these pathways rather than on “cellular energy production” itself[6][5][8][1].
