| Comments |
"Table 2.2 lists ion concentrations and transmembrane potentials for a variety of cell types." "In many animal cells, the chloride and potassium ions have such oppositely poised concentration ratios [with potassium high and chloride low, intracellularly (see Table 2.2)], both ions often being not far from equilibrium with the electrical potential across the membrane. If the concentration gradient for S is not that given by Eq. (2.5), the system has the capacity to perform work, which it will do if the means of doing so are provided." Table gives Ion concentrations, calculated equilibrium potential and measured transmembrane potential |
