WebStimulated by the action of the ions on its receptors, the pump transports them in opposite directions against their concentration gradients. If equal amounts of Na + and K + were transported across the membrane by the pump, the net charge transfer would be zero; there would be no net flow of current and no effect on the membrane potential. WebThe pressure gradient is directly dependent upon blood vessel radius which essentially controls blood flow. The bigger the blood vessel radius, the more blood flow or fluid flow. …
