WebSteps in generating action potential. Action potentials describe the change from negative to positive membrane potential. For this change to occur, the stimulus must surpass the … Nearly all cell membranes in animals, plants and fungi maintain a voltage difference between the exterior and interior of the cell, called the membrane potential. A typical voltage across an animal cell membrane is −70 mV. This means that the interior of the cell has a negative voltage relative to the exterior. In most types of cells, the membrane potential usually stays fairly constant. S…
