Question

Many biological e¯ transfer events are based on the quantum tunneling mechanism (e.g. as the e¯ transfers in the mitochondria or chloroplasts membranes). For a certain combination of e¯ donor and acceptor (co-factors), the rate of e¯ tunneling is given by eq 9.11 (the Text) with k=7 1/nm. By what factor does the e¯ tunneling rate decrease as the distance between the two co-factors change from 1.0 nm to 2.0 nm?
