Enzyme Action Testing Catalase ActivityEnzymes are proteins that serve as catalysts and accelerate chemical reactions in living organisms Enzymes accomplish this by lowering the energy of activation of the organism it is acting upon however enzymes will only lower the energy of activation for specific organisms reducing chaotic chemical reactions The reaction is carried out in its entirety in the active site of the enzyme The substrate organism acted upon binds itself into the active site of the enzyme and the chemical process begins The enzymes active site will reform itself for the substrate in order to form a perfect bond this is called induced fit This is only one of the changes that could occur to accommodate the substrate For example the enzyme might change the pH levels to promote the reaction There are numerous factors that can affect the rate of the chemical changes four have the greatest affect They are the concentration of the enzyme the temperature the pH level and the salt concentration The higher the concentration of the enzyme the faster the rate of change there is upon the organism The temperature affects the rate in this way each enzyme has a specific temperature in which it functions at an optimum rate too low of a temperature the enzyme will not function at all However too high of a temperature produces the same results Third the pH level will affect the rate H and OH- ions can cause the organism to change shape and become deformed denature and cause abnormal functionality Finally salt concentration will affect the rate of chemical change because the inorganic ions in salts will interfere with ionic bonds in protein molecules There are very few factors that influence the function of the enzyme Some enzymes require cofactors substances that assist the chemical reaction Chemical inhibitors can inhibit the enzymes functionality 1 by attaching itself to the active site competitive inhibitors blocking the substrate 2 by attaching
