Explain where sodium and potassium ions are located relative to a muscle cell during resting membrane potential
What will be an ideal response?
A membrane is considered polarized in its resting state when opposite charges are located on either side of the membrane. At rest, the concentration of sodium ions is greater in the extracellular fluid and lower in the cytosol due to the actions of the Na+/K+ ATPase pump. Potassium ion concentration is higher in the cytosol and lower in the extracellular fluid at rest.
