@historylab8: Your body is powered by microscopic rotary engines spinning at 10,000 RPM. ⚡️🏎️ The Torsion Spring: inside your mitochondria, the central stalk of ATP synthase acts as a mechanical torsion spring. As protons spin the engine's core, the stalk twists and stores mechanical elastic energy—then snaps forward to manufacture ATP energy in precise, high-velocity bursts. Peak nanoscale mechanics. 🦾🧬 #Biophysics #BioEngineering #ScienceTok #AnatomyFacts #HumanHardware
