Which is TRUE about neuronal membrane electrical and concentration gradients at the peak of the action potential? The electrical gradient is in a direction that would tend to move K+ out of the cell. The concentration gradient for K+ is in a direction that would tend to move it into the cell. The concentration gradient for K+ greatly increases compared to at rest. O The concentration gradient for Na+ is in a direction that would tend to move it out of the cell.
