  2. Mineral absorption - Wikipedia

    en.wikipedia.org/wiki/Mineral_absorption

    In plants and animals, mineral absorption, also called mineral uptake is the way in which minerals enter the cellular material, typically following the same pathway as water. In plants, the entrance portal for mineral uptake is usually through the roots. Some mineral ions diffuse in-between the cells. In contrast to water, some minerals are ...

  3. Calcium metabolism - Wikipedia

    en.wikipedia.org/wiki/Calcium_metabolism

    Calcium is the most abundant mineral in the human body. [3] The average adult body contains in total approximately 1 kg, 99% in the skeleton in the form of calcium phosphate salts. [ 3 ] The extracellular fluid (ECF) contains approximately 22 mmol, of which about 9 mmol is in the plasma . [ 4 ]

  4. Template:Metabolic pathways - Wikipedia

    en.wikipedia.org/wiki/Template:Metabolic_pathways

    This page is the template for the metabolic pathways template. This template should be used to illustrate the general 'shape' of metabolism within the cell. This template is part of the Metabolic Pathways task force. This template has been largely superseded by {{Metabolic metro}} but is kept as an archive

  5. Human iron metabolism - Wikipedia

    en.wikipedia.org/wiki/Human_iron_metabolism

    Absorption of dietary iron in iron salt form (as in most supplements) varies somewhat according to the body's need for iron, and is usually between 10% and 20% of iron intake. Absorption of iron from animal products, and some plant products, is in the form of heme iron, and is more efficient, allowing absorption of from 15% to 35% of intake.

  6. Metabolic pathway - Wikipedia

    en.wikipedia.org/wiki/Metabolic_pathway

    An anabolic pathway is a biosynthetic pathway, meaning that it combines smaller molecules to form larger and more complex ones. [ 10 ] : 570 An example is the reversed pathway of glycolysis, otherwise known as gluconeogenesis , which occurs in the liver and sometimes in the kidney to maintain proper glucose concentration in the blood and supply ...

  7. Sarcoplasmic reticulum - Wikipedia

    en.wikipedia.org/wiki/Sarcoplasmic_reticulum

    The longitudinal SR are thinner projects, that run between the terminal cisternae/junctional SR, and are the location where ion channels necessary for calcium ion absorption are most abundant. [4] These processes are explained in more detail below and are fundamental for the process of excitation-contraction coupling in skeletal , cardiac and ...

  8. Biomineralization - Wikipedia

    en.wikipedia.org/wiki/Biomineralization

    Fossil skeletal parts from extinct belemnite cephalopods of the Jurassic – these contain mineralized calcite and aragonite.. Biomineralization, also written biomineralisation, is the process by which living organisms produce minerals, [a] often resulting in hardened or stiffened mineralized tissues.

  9. Human digestive system - Wikipedia

    en.wikipedia.org/wiki/Human_digestive_system

    The parietal cells in the fundus of the stomach, produce a glycoprotein called intrinsic factor which is essential for the absorption of vitamin B12. Vitamin B12 (cobalamin), is carried to, and through the stomach, bound to a glycoprotein secreted by the salivary glands – transcobalamin I also called haptocorrin, which protects the acid ...
