Of related interest, in the light of recent research, is recognition that the source of energy in biological motion -- the capacity of muscles to generate pulling force -- may be explicable in terms of quantum tunnelling. Living cells are indeed capable of "burning" biological fuel to generate energy for muscle contraction. It is enzymes which accelrate the rate of chemical reactions -- with billion-fold enhancements of chemical reactions being common. Enzymes are now understood -- through research on on the structure and dynamics of biomolecules at the atomic level -- to function in a domain governed by the rules of quantum mechanics and to take advantage of quantum tunnelling to achieve things that would normally be considered impossible. The dynamics of the enzyme activity promote the quantum tunnelling event in order to accelerate the reaction rate -- the enzyme needs quantum mechanics to perform its function.
