Sodium-potassium pumps move two potassium ions inside the cell as three sodium ions are pumped out to maintain the negatively-charged membrane inside the cell; this helps maintain the resting potential.
Considering this, what is a resting membrane potential and how is it generated?
Ion affection of resting membrane potential[ RMP is created by the distribution of ions and its diffusion across the membrane. Potassium ions are important for RMP because of its active transport, which increase more its concentration inside the cell.
What is the resting membrane potential determined by?
In most neurons the resting potential has a value of approximately −70 mV. The resting potential is mostly determined by the concentrations of the ions in the fluids on both sides of the cell membrane and the ion transport proteins that are in the cell membrane.
What process establishes the resting membrane potential?
The sodium potassium pump establishes an electrochemical gradient and the potassium ions flow from the areas of high concentration inside the cell to areas of low concentration outside the cell. These processes establish the resting membrane potential.
