ABSTRACT: An enzyme is a protein which functions as an organic catalyst, which allows a particular reaction to occur without using itself up in the process. Without enzymes, most reactions in a cell would not occur. Enzymes function best in an acidic environment as do catalase, however the correct concentration of an acidic solution is needed to ensure the most efficient reaction. Placing a catalase enzyme into a solution which is slightly acidic (less than …showed first 75 words of 726 total…

The molar concentration of the hydrochloric acid may have also affected the outcome of the lab because of its strength. In the lab .5mol/L was used, but with a weaker concentration the results might have been more visible because the effects may have been more pronounced and the concept more easily grasped.
