    "abstract": "We study a simple quantum mechanical symmetric donor-acceptor model for\nelectron transfer (ET) with coupling to internal deformations. The model\ncontains several basic properties found in biological ET in enzymes and\nphotosynthetic centers; it produces tunnelling with hysteresis thus providing a\nsimple explanation for the slowness of the reversed rate and the near 100%\nefficiency of ET in many biological systems. The model also provides a\nconceptual framework for the development of molecular electronics memory\nelements based on electrostatic architectures.",
