Which ion has greatest influence on resting membrane potential? Potassium (potassium has more leak channels on the membrane than sodium, which is why potassium has a higher permeability value and has more impact of resting membrane potential) Concerning resting membrane potential, the inside of the membrane is _______ compared to the ________ charged outside. negative, positively. T or F: The diffusion of K+ and Na+ down their chemical gradients contributes to the resting membrane potenti...
