Neuron cells generate electrical signals using concentration gradients across membranes. Assuming a potassium ion concentration of 0.00300 M inside the cell and a concentration of 0.135 M outside the cell, what is the electrical potential across the cell membrane? Body temperature is 310 K. The sign identifies the change in the electrical potential across the membrane and determines which way the ions flow.
