Reestablishment of the resting membrane potential occurs throughMultiple ChoiceActive transport of sodium and potassium ionsDiffusion of sodium and potassium ionsActive transport of only sodium ionsActive transport of only potassium ions
Solution
The reestablishment of the resting membrane potential occurs through the active transport of sodium and potassium ions. This process is facilitated by the sodium-potassium pump, which actively moves 3 sodium ions out of the cell and 2 potassium ions into the cell. This helps to maintain the negative charge inside the cell, thus reestablishing the resting membrane potential.

Although the membrane of a "resting" neuron is highly permeable to potassium ions, its membrane potential does not exactly match the equilibrium potential for potassium because the neuronal membrane is alsofully permeable to sodium ions.slightly permeable to sodium ions.highly permeable to chloride ions.fully permeable to calcium ions.impermeable to sodium ions.SubmitRequest Answer
At resting membrane potential, voltage-gated potassium ion channels are open.
The maintenance of a resting membrane potential is due to three factors:(1) The concentration of K+ the membrane is than that the membrane.(2) The concentration of Na+ the membrane is than that the membrane.(3) The membrane is permeable to K+ than Na+.
Resting membrane potential:Results in high concentrations of Na+ on the outside of the cellIs maintained by the sodium/potassium ATPase pump continuously pumping Na+ into the cellResults in the outside of the cell having a -70mV polarity relative to the inside.Is the process by which cells communicate
The resting membrane potential depends on two main factors that influence the magnitude and direction of Na+ and K+ diffusion across the plasmid membrane.What are these two factors?
