Final Lab Catalase Formal Lab: Introduction: An enzyme is a biological catalyst that alters the rate of reaction without being consumed or changing the reaction itself. Enzymes are also proteins; they take on a three- dimensional shape which forms a specific active site. An active site is a location where a substrate binds with an enzyme. Usually they are a pocket or groove in the three- dimensional shape of the protein. Next to the active site, but still a great distance away is the Allosteric site, sites containing receptors. The allosteric site is a part of enzyme activation, ‘the difference between the energy level of the transition state and the potential energy of reacting molecules.’ Another part of the enzyme activation is the activator, which links itself to the allosteric site; it changes the shape of the enzyme letting the active site to allow the substrate to latch on. Many cells can produce hydrogen peroxide as a toxic; this takes place by products from their own metabolic reaction. Another product cells can produce is catalase enzyme which helps breakdown hydrogen peroxide into water and O2 gas. Catalase enzyme 2 Hydrogen peroxide 2 water + oxygen + heat energy Every type of animal on Earth uses catalase in their organs, but it is commonly known that liver has the highest concentration. The reason why scientist say liver has the highest concentration then all the other organs is because the liver’s function is to break down toxins present in the blood. This goes hand in hand with cells producing hydrogen peroxide a toxin. The purpose of this lab experiment was to
