"Ion pump" redirects here. For pumps that reduce pressure, see Ion pump (physics). An ion pump works by creating an Electric field across a fluid containing ions

In biology, an ion transporter, also called an ion pump, is a transmembrane protein that moves ions across a plasma membrane against their concentration gradient, in contrast to ion channels, where ions go through passive transport

Energy source

Such ion pumps can use energy from a variety of sources, including ATP or the concentration gradient of another ion (sometimes called an "ion exchanger"). A transmembrane protein is a Protein that spans the entire Biological membrane. The cell membrane (also called the plasma membrane, plasmalemma, or "phospholipid bilayer" is a Selectively permeable Lipid bilayer Diffusion is the net movement of particles (typically molecules from an area of high concentration to an area of low concentration by uncoordinated random movement Ion channels are pore-forming Proteins that help establish and control the small Voltage Gradient across the Plasma membrane of all living Passive transport means moving biochemicals and atomic or molecular substances across the Cell membrane. Adenosine-5'-triphosphate ( ATP) is a multifunctional Nucleotide that is most important as a " molecular currency" of intracellular Energy Diffusion is the net movement of particles (typically molecules from an area of high concentration to an area of low concentration by uncoordinated random movement Ion exchange is an exchange of Ions between two Electrolytes or between an electrolyte Solution and a complex. Symporters transport an ions down their concentration gradient to fuel the transport of another type of ion in the same direction, while antiporters also use the concentration gradient in this same manner but transport in the opposite direction. A symporter is an Integral membrane protein that is involved in movement of two or more different molecules or ions across a phospholipid membrane such as the Plasma membrane An antiporter (also called exchanger or counter-transporter) is an Integral membrane protein which is involved in Secondary active transport For a more detailed description of one particular kind of ion pump, see Na⁺/K⁺-ATPase.
