Which of the following modifications would make the resting potential of the neuron more positive? (select all that apply) Increase the extracellular Ca2+ concentration Increase the intracellular Ca2+ concentration Increase the extracellular Cl- concentration Increase the intracellular Cl- concentration
Added by Devin G.
Step 1
Increasing the extracellular Ca2+ concentration: This would not make the resting potential of the neuron more positive. The resting potential is primarily determined by the concentrations of K+ and Na+, not Ca2+. Show more…

Changes in ion conductance or ion concentration can alter the resting membrane potential of a cell. For each of the following conditions below, discuss whether each condition would cause hyperpolarization, depolarization, or very little change in the resting membrane potential, and the reason for this change. Condition: a) Increase in extracellular K + concentration b) Increase in extracellular Na+ concentration c) Increase in K+ permeability d) Increase in Na+ permeability
