The sodium/potassium pump requires energy in the form of adenosine triphosphate (ATP), so it is also referred to as an ATPase. As was explained in the cell chapter, the concentration of Na + is higher outside the cell than inside, and the concentration of K + is higher inside the cell than outside. That means that this pump is moving the ions ...

Figure 3.9 Sodium-Potassium Pump The sodium-potassium pump is found in many cell (plasma) membranes. Powered by ATP, the pump moves sodium and potassium ions in opposite directions, each against its concentration gradient. In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell.

In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell.

An example of active transport is the sodium/potassium ion pump, explained in the diagram above. This pump uses energy from ATP (adenosine trisphosphate - the molecule that carries the cell's store of usable energy). The pump is a membrane protein and it pumps two potasium ions (K+) into the cell for every three sodium ions (Na+) that it pumps ...

The electrical difference across the membrane of the neuron is called its resting potential.. The resting potential is created by a transport protein called the sodium-potassium pump.This protein moves large numbers of sodium ions (Na +) outside the cell, creating the positive charge.At the same time, the protein moves some potassium (K +) ions into the cell’s cytoplasm.

The sodium-potassium pumps in the membrane of the axon continually pump 3 Na + ions out the cell for every 2 K + ions moved into the cell against a concentration gradient, using energy provided by a large number of mitochondria found in the neurone. Due to the concentration gradients, Na + ions tend to leak back into the cell, and K + ions tend ...

Function Thick Ascending Limb. The primary site of sodium reabsorption in the Loop of Henle is the thick ascending limb (TAL). The TAL is impermeable to water.Sodium (Na +) reabsorption is active- the driver is the Na + /K + ATPase on the basolateral membrane which actively pumps three Na + ions out the cell into the interstitium and two potassium(K +) ions into the cell.

This large difference in concentration between intra- and extracellular fluid is maintained by enzymes (Na-K-ATPase) that actively pump potassium into the cell and sodium out, to maintain a serum potassium concentration between 3.5 and 5.3 mmol/L.

Although sodium and potassium can “leak” through “pores” into and out of cells, respectively, the high levels of potassium and low levels of sodium in the ICF are maintained by sodium-potassium pumps in the cell membranes. These pumps use the energy supplied by ATP to pump sodium out of the cell and potassium into the cell.
