Question

According to Hodgkin and Huxley's calculations, the resting potential across the neural membrane is -70mV. This potential is primarily maintained by the unequal distribution of K+ ions across the membrane, with a higher concentration of K+ ions inside the cell, and the electrostatic force drawing them out causing a net negative charge on the inside of the cell. Therefore, choice B is also correct as it describes the electrostatic force required to maintain the resting distribution of K+ ions. Option C cannot be correct as the resting potential for Na+ ions is about +60 mV, which is not negative. Option D cannot be correct as option C is incorrect. Thus, option E is the best choice as it correctly identifies the electrostatic force required to maintain the resting potential of both Cl- and K+ ions.
