Krebs Cycle

The Krebs cycle maps how cells harvest energy with remarkable efficiency. Hans Krebs's 1937 elucidation of this 10-step pathway reveals that each turn produces 10 molecules of ATP—the cell's energy currency—making it 50% more efficient than the anaerobic glycolysis that precedes it. Compared to the Human Genome Project (#6), which provided a static blueprint, the Krebs cycle remains the foundational dynamic process for life, influencing treatments for metabolic disorders and cancer by identifying key enzymatic targets.
