  2. Water splitting - Wikipedia

    en.wikipedia.org/wiki/Water_splitting

    In thermolysis, water molecules split into hydrogen and oxygen. For example, at 2,200 °C (2,470 K; 3,990 °F) about three percent of all H 2 O are dissociated into various combinations of hydrogen and oxygen atoms, mostly H, H 2, O, O 2, and OH. Other reaction products like H 2 O 2 or HO 2 remain minor. At the very high temperature of 3,000 ...

  3. Phosphatase - Wikipedia

    en.wikipedia.org/wiki/Phosphatase

    The general reaction catalyzed by a phosphatase enzyme. Phosphatases catalyze the hydrolysis of a phosphomonoester, removing a phosphate moiety from the substrate. Water is split in the reaction, with the -OH group attaching to the phosphate ion, and the H+ protonating the hydroxyl group of the other product. The net result of the reaction is ...

  4. Hydrolysis - Wikipedia

    en.wikipedia.org/wiki/Hydrolysis

    When a carbohydrate is broken into its component sugar molecules by hydrolysis (e.g., sucrose being broken down into glucose and fructose), this is recognized as saccharification. [2] Hydrolysis reactions can be the reverse of a condensation reaction in which two molecules join into a larger one and eject a water molecule. Thus hydrolysis adds ...

  5. Photosystem II - Wikipedia

    en.wikipedia.org/wiki/Photosystem_II

    In 2011 the OEC of PSII was resolved to a level of 1.9Å revealing five oxygen atoms serving as oxo bridges linking the five metal atoms and four water molecules bound to the Mn 4 CaO 5 cluster; more than 1,300 water molecules were found in each photosystem II monomer, some forming extensive hydrogen-bonding networks that may serve as channels ...

  6. Enzymatic hydrolysis - Wikipedia

    en.wikipedia.org/wiki/Enzymatic_hydrolysis

    In biochemistry, enzymatic hydrolysis is a process in which enzymes facilitate the cleavage of bonds in molecules with the addition of the elements of water (i.e. hydrolysis). It plays an important role in the digestion of food. [1] It may be used to help provide renewable energy, as with cellulosic ethanol. [2]

  7. Hydrolase - Wikipedia

    en.wikipedia.org/wiki/Hydrolase

    Hydrolase enzymes are important for the body because they have degradative properties. In lipids, lipases contribute to the breakdown of fats and lipoproteins and other larger molecules into smaller molecules like fatty acids and glycerol. Fatty acids and other small molecules are used for synthesis and as a source of energy. [1]

  8. Electrolysis of water - Wikipedia

    en.wikipedia.org/wiki/Electrolysis_of_water

    Electrolysis of water is using electricity to split water into oxygen (O 2) and hydrogen (H 2) gas by electrolysis. Hydrogen gas released in this way can be used as hydrogen fuel, but must be kept apart from the oxygen as the mixture would be extremely explosive.

  9. ATP hydrolysis - Wikipedia

    en.wikipedia.org/wiki/ATP_hydrolysis

    Structure of ATP Structure of ADP Four possible resonance structures for inorganic phosphate. ATP hydrolysis is the catabolic reaction process by which chemical energy that has been stored in the high-energy phosphoanhydride bonds in adenosine triphosphate (ATP) is released after splitting these bonds, for example in muscles, by producing work in the form of mechanical energy.
