ATP SYNTHESIS. “Conventional biological models described the electrons as hopping from molecule to molecule within mitochondria, but — once again — this simple picture cannot account for the speed at which ATP is spit out… a (new) model in which, rather than hopping, the electrons exist in a quantum superposition, smeared out at once across all the molecules in the ATP production line…calculations predicted a boosted ATP production rate, as seen in experiments.”
