How is resting potential established

Web25 mrt. 2024 · The resting membrane potential of a cell is maintained by the sodium-potassium pump and is possible because the membrane itself is not very permeable to ions. The sodium-potassium pump uses the energy stored in ATP to pump sodium and potassium across the membrane. Web13 aug. 2024 · Figure 7.10. The (a) resting membrane potential is a result of different concentrations of Na+ and K+ ions inside and outside the cell. A nerve impulse causes Na+ to enter the cell, resulting in (b) depolarization. At the peak action potential, K+ channels open and the cell becomes (c) hyperpolarized.
