Abstract
DEVAULT et al.1 have proposed that electron transfer through biological structures over distances of a few tens of Ångstroms occurs by tunnelling, the height of the energy barrier stipulated being 1 eV. Similarly, Wei2 has suggested that electron tunnelling through the nerve membrane is involved in producing the N-shaped current voltage characteristics observed in, for example, squid axons3 and other membranes4. The question of the relative probability of the electron going over instead of through the barrier—in other words, electron transfer by hopping—has, however, not yet been resolved.
