  2. Potassium in biology - Wikipedia

    en.wikipedia.org/wiki/Potassium_in_biology

    The sodiumpotassium 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 cycle - Wikipedia

    en.wikipedia.org/wiki/Potassium_cycle

    The most abundant ion in plant cells is the potassium ion. [2] Plants take up potassium for plant growth and function. A portion of potassium uptake in plants can be attributed to weathering of primary minerals, but plants can also ‘pump’ potassium from deeper soil layers to increase levels of surface K. [2] Potassium stored in plant matter can be returned to the soil during decomposition ...

  4. Sodium in biology - Wikipedia

    en.wikipedia.org/wiki/Sodium_in_biology

    The sodiumpotassium pump, a critical enzyme for regulating sodium and potassium levels in cells. Sodium ions (Na +) are necessary in small amounts for some types of plants, [1] but sodium as a nutrient is more generally needed in larger amounts [1] by animals, due to their use of it for generation of nerve impulses and for maintenance of electrolyte balance and fluid balance.

  5. 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 ...

  6. Plant nutrition - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrition

    Plant nutrition is the study of the chemical elements and compounds necessary for plant growth and reproduction, plant metabolism and their external supply. In its absence the plant is unable to complete a normal life cycle, or that the element is part of some essential plant constituent or metabolite .

  7. Biological roles of the elements - Wikipedia

    It is selectively taken up by plants, so there are a variety of possible roles in plant metabolism. [44] There is limited medical use. [11] Inhibits iron uptake and metabolism in a variety of plants and bacteria. [44] germanium: 32: 2a: Some plants will take it up, but it has no known metabolic role. [11] Some salts are deadly to some bacteria ...

  8. Nutrient - Wikipedia

    en.wikipedia.org/wiki/Nutrient

    Dietary minerals, such as potassium, sodium, and iron, are elements native to Earth, and cannot be synthesized. They are required in the diet in microgram or milligram amounts. As plants obtain minerals from the soil, dietary minerals derive directly from plants consumed or indirectly from edible animal sources. [8]

    Table salt (sodium chloride) is the main dietary source. hypochloremia / hyperchloremia: Sodium: 1500 2300; NE: A systemic electrolyte and is essential in coregulating ATP with potassium Table salt (sodium chloride, the main source), sea vegetables, milk, and spinach. hyponatremia / hypernatremia: Calcium: 1000 2500; 2500
