Detailed explanation-1: -[3][4] The Na+K+-ATPase pump helps to maintain osmotic equilibrium and membrane potential in cells. The sodium and potassium move against the concentration gradients. The Na+ K+-ATPase pump maintains the gradient of a higher concentration of sodium extracellularly and a higher level of potassium intracellularly.
Detailed explanation-2: -Passive transport: membrane channels The sodium-potassium pump sets the membrane potential of the neuron by keeping the concentrations of Na+ and K+ at constant disequilibrium.
Detailed explanation-3: -Hyperkalemia☆ The primary intracellular electrolyte, potassium produces a high osmotic pressure to maintain cell volume. Potassium is essential for maintaining a normal cell resting membrane potential and for generating and propagating action potentials in excitable tissues.
