This table below provides approximate values for theintracellular and extracellular concentrations in unit mmol/L forsodium, potassium, and chlorine ions in a frog muscle with aresting potential difference of −98 mV and for the squid axon witha resting potential difference of −70 mV. Calculate the equilibriumpotential difference (in mV) for each ion species in both cases at17°C.
Table:
Frog muscle (intracellular, extracellular)
Na+ = 9-13, 120
K+ = 140, 2.5
Cl- = 3.5, 120
Squid Axon (intracellular, extracellular)
Na+ = 50, 440
K+ = 400, 20
Cl- = 40-100, 560
