  2. Physisorption - Wikipedia

    en.wikipedia.org/wiki/Physisorption

    Physisorption is a general phenomenon and occurs in any solid/fluid or solid/gas system. Chemisorption is characterized by chemical specificity. In physisorption, perturbation of the electronic states of adsorbent and adsorbate is minimal.

  3. Exocytosis - Wikipedia

    en.wikipedia.org/wiki/Exocytosis

    Porosomes are permanent cup-shaped lipoprotein structures at the cell plasma membrane, where secretory vesicles transiently dock and fuse to release intra-vesicular contents from the cell. In exocytosis, membrane-bound secretory vesicles are carried to the cell membrane , where they dock and fuse at porosomes and their contents (i.e., water ...

  4. Polymer adsorption - Wikipedia

    en.wikipedia.org/wiki/Polymer_adsorption

    Protein adsorption influences the interactions that occur at the tissue-implant interface. Protein adsorption can lead to blood clots, the foreign-body response and ultimately the degradation of the device. In order to counter-act the effects of protein adsorption, implants are often coated with a polymer coating to decrease protein adsorption.

  5. Adsorption - Wikipedia

    en.wikipedia.org/wiki/Adsorption

    The function is not adequate at very high pressure because in reality / has an asymptotic maximum as pressure increases without bound. As the temperature increases, the constants k {\displaystyle k} and n {\displaystyle n} change to reflect the empirical observation that the quantity adsorbed rises more slowly and higher pressures are required ...

  6. Cellular respiration - Wikipedia

    en.wikipedia.org/wiki/Cellular_respiration

    Cellular respiration may be described as a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from nutrients into ATP, and then release waste products. [1] Cellular respiration is a vital process that occurs in the cells of all [[plants and some bacteria ]].

  7. Langmuir adsorption model - Wikipedia

    en.wikipedia.org/wiki/Langmuir_adsorption_model

    The terms in the bracket give the total partition function of the adsorbed molecules by taking a product of the individual partition functions (refer to Partition function of subsystems). The 1 / N A ! {\displaystyle 1/N_{A}!} factor accounts for the overcounting arising due to the indistinguishable nature of the adsorbates.

  8. Pentose phosphate pathway - Wikipedia

    en.wikipedia.org/wiki/Pentose_phosphate_pathway

    In mammals, the PPP occurs exclusively in the cytoplasm. In humans, it is found to be most active in the liver, mammary glands, and adrenal cortex. [ citation needed ] The PPP is one of the three main ways the body creates molecules with reducing power, accounting for approximately 60% of NADPH production in humans.

  9. Catabolism - Wikipedia

    en.wikipedia.org/wiki/Catabolism

    Released from alpha cells in the pancreas either when starving or when the body needs to generate additional energy; it stimulates the breakdown of glycogen in the liver to increase blood glucose levels; its effect is the opposite of insulin; glucagon and insulin are a part of a negative-feedback system that stabilizes blood glucose levels ...
