Collective aspects of conformons and the electron transfer chain

A set of interacting harmonic oscillators is used as a model to define a low frequency collective mode in protein molecules. Such a mode may arise from electron-phonon interactions in second order perturbation theory. The mathematical scheme is analogous to those used in the theory of carcadian rhythms and in the theory of superconductivity. This collective mode may receive energy from electrons in the electron transfer chain (conformon) and pass the energy on to other similar modes. The low frequency of the mode leads to slow reactions, in agreement with experimental data. The model is compatible with some general characteristics of the electron transfer chain and its constituents: high thermodynamic efficiency, redox pools, redox switches, entatic states and conformational free energy transfer.
