| Comments |
"In the case of mitochondrial
porin [primary source], the channel size estimated from the cutoff
size for permeating molecules agrees well with
the size calculated from the channel conductance,
assuming that ions diffuse through a pore of cylindrical
geometry, with a conductivity equal to
that of the aqueous medium. These hole sizes are
calculated to be quite large, 20-30 Å in diameter,
and the transport rates are enormous, 10^8-10^9 ions
per sec, at 100mV." |
