Your body hydrolyzes ~10²⁶ ATP molecules daily— (≈ recycling your body mass in ATP ~1000 times). At 55 kJ/mol under cellular conditions (vs 30.5 kJ/mol standard), this molecular currency runs on a 25 kJ premium. Kleiber's law shows metabolic rate scales as M^0.75, not M.

Bond energy across 17 molecules fits the universal Morse potential model: E(r) = D_e[1 - e^{-a(r - r_e)}]^2. Computed in R, results confirm quantum predictions:
• Shorter bonds = stronger bonds
• Bond order boosts stability
