  2. Potassium in biology - Wikipedia

    en.wikipedia.org/wiki/Potassium_in_biology

    The sodium–potassium pump a critical enzyme for regulating sodium and potassium levels in cells. Potassium is the main intracellular ion for all types of cells, while having a major role in maintenance of fluid and electrolyte balance. [1] [2] Potassium is necessary for the function of all living cells and is thus present in all plant and ...

  3. Potassium - Wikipedia

    en.wikipedia.org/wiki/Potassium

    The ion transport system moves potassium across the cell membrane using two mechanisms. One is active and pumps sodium out of, and potassium into, the cell. The other is passive and allows potassium to leak out of the cell. Potassium and sodium cations influence fluid distribution between intracellular and extracellular compartments by osmotic ...

  4. Transcellular transport - Wikipedia

    en.wikipedia.org/wiki/Transcellular_transport

    There are two types of active transport, primary active transport and secondary active transport. [citation needed] Primary active transport uses adenosine triphosphate (ATP) to move specific molecules and solutes against its concentration gradient. Examples of molecules that follow this process are potassium K +, sodium Na +, and calcium Ca 2+.

  5. Transport protein - Wikipedia

    en.wikipedia.org/wiki/Transport_protein

    (4) The transporter opens to the inside while both the potassium ions and the phosphorylated group leaves it. A transport protein (variously referred to as a transmembrane pump , transporter , escort protein , acid transport protein , cation transport protein , or anion transport protein ) is a protein that serves the function of moving other ...

  6. Sodium–potassium pump - Wikipedia

    en.wikipedia.org/wiki/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.

  7. Active transport - Wikipedia

    en.wikipedia.org/wiki/Active_transport

    Active transport is essential for various physiological processes, such as nutrient uptake, hormone secretion, and nerve impulse transmission. For example, the sodium-potassium pump uses ATP to pump sodium ions out of the cell and potassium ions into the cell, maintaining a concentration gradient essential for cellular function. Active ...

    Oxygen and nutrient supply: Potassium helps regulate blood flow to the brain, ensuring that brain cells receive an adequate supply of oxygen and nutrients. The brain is highly metabolically active ...

  9. Membrane transport protein - Wikipedia

    en.wikipedia.org/wiki/Membrane_transport_protein

    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. Active transport is the movement of a substance across a membrane against its concentration gradient. This ...
