摘要：

The problems of the description of a protein matrix as a medium for electron transfer in biological systems are described. It is not the uncertainty in rate constants but that of measuring donor-acceptor distances or of pathway lengths which makes it impossible to decide between the merits of these two approximations to a full quantum-mechanical treatment of the matrix. However, proteins do not seem to have designed pathways to fulfil their functions but just separations of donors and accepters in space which then allows gated flow in mobile structures.
