See: The vibrational theory of olfaction for the win The same kinds of amino acid substitutions that control the separations and interactions of side chains in fluorescent proteins also play an essential role in tuning the proposed mechanism for vibration detection—inelastic electron tunneling. Life literally runs on electron tunneling through the respiratory chain complexes in mitochondria.
