• A Guaiacol Dye-Coupled Reaction Reports That Catalytic Activity of Peroxidase Isolated from Fresh Turnip (Brassica Rapa) Increases as Temperature Rises.
    Enzymes are proteins which serve to reduce the activation energy required for biological reactions (Russell and others 2010). This allows biologically important chemical reactions to occur rapidly enough to allow cells to carry out their life processes (Russell and others 2010). Enzymes are made of one...

  • Temperature's Effect Against the Irreversible Denaturation of Peroxidase
    Abstract: Enzyme-catalyzed hydrolysis reaction occurs when an enzyme cleaves glycosidic linkage where a substrate binds to active site forming an enzyme-substrate complex. By adding water to the enzyme-substrate complex, products are release. One of the main factor that effect enzyme-catalyzed reactions...
