  • The lipid bilayer that forms the wall of a neuron (or glial cell) is not permeable to charged ions.  However, there are a number of types of ion channels that allow ions to move down their concentration gradient across the membrane, and ion transporters that allow ions to move against their concentration gradient (from low concentration to high concentration).  One of the best examples of an ion transporter is the sodium-potassium pump (also called Na+/K+ pump or Na+/K+ ATPase), which pumps potassium into a cell and sodium out of a cell, both against their concentration gradients, with the use of ATP to provide energy for the process.   The actions of this pump sequester K+ inside of neurons and extrude Na+ from neurons (in other words, the sodium potassium pump causes intracellular K+ to be high and intracellular Na+ to be low, relative to the extracellular fluid).

  • The resting membrane potential is the result of the movement of several different ion species through various ion channels and transporters (uniporters, cotransporters, and pumps) in the plasma membrane. These movements result in different electrostatic charges across the cell membrane. Neurons and muscle cells are excitable such that these cell types can transition from a resting state to an excited state. The resting membrane potential of a cell is defined as the electrical potential difference across the plasma membrane when the cell is in a non-excited state. Traditionally, the electrical potential difference across a cell membrane is expressed by its value inside the cell relative to the extracellular environment. [1][2]

  • First, Na+ ions bind to high-affinity sites inside the cell. This binding stimulates the hydrolysis of ATP and phosphorylation of the pump, inducing a ...

  • The internal composition of the cell is maintained because the plasma membrane is selectively permeable to small molecules. Most biological molecules are unable to diffuse through the phospholipid bilayer, so the plasma membrane forms a barrier that blocks the free exchange of molecules between the cytoplasm and the external environment of the cell. Specific transport proteins (carrier proteins and channel proteins) then mediate the selective passage of small molecules across the membrane, allowing the cell to control the composition of its cytoplasm.

  • The sodium-potassium pump (also known as the Na+/K+ pump or Na+/K+-ATPase) is a protein pump found in the cell membrane of neurons (and other cells). Its main function is to transport sodium ions out of the cell and potassium ions into the cell. To understand why this is an important physiological mechanism in neurons, we need to first talk a bit about the concentrations of ions inside and outside of neurons, and why maintaining this concentration is important to how neurons work.
