  Quantum processes have been confirmed for various biological phenomena. Here
we model a quantum process in cells based on coherent waves of established
ultrafast energy transfers in water. We compute wave speed, ~156 km/s, and
wavelength, ~9.3 nm, and determine that the waves retain local coherence. The
model is compared with observations and diverse numerical applications lend
support to the hypothesis that rapid energy transfers in water are
characteristic of living cells. Close agreements are found for the dipole
moment of water dimers, microwave radiation on yeast, and the Kleiber law of
metabolic rates. We find a sphere with diameter ~20 nm is a lower bound for
life in this theory. The quantum properties of the model suggest that cellular
chemistry favors reactions that support perpetuation of the energy waves
