Physics

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
