Enzymes are one of an important function to the body. An enzyme is a catalyst that speeds up chemical reactions without being used up in the process (Leady 2017). In simpler terms, it is a substance that is used for chemical reactions to accelerate the chemical reaction, and create a new product from the previous substance without changing the chemical compounds. Not all of the enzymes work the same. Some of the enzymes can either be affected by a different pH, or a different substrate concentration. When conducting experiments, the pH, or the substrates have to be similar because if the products are in a different area, then the results will be completely different. This is why experiments conducted have to have a similar area. The experiment conducted is about the different levels of concentration. The question is will different levels of substrate concentration and pH affect enzyme function? The hypothesis is that the pH with a higher pH will effect it more, and a substrate concentration with a higher substrate concentration will have a higher effect. The prediction points to the area of the pH9 having the greatest effect out of the 4 groups, and a 12% H2O2 concentration also having the greatest effect out of the 4 groups.
• Methods: The method I used in the experiment was followed by the lab manual of “Fundamentals of Life Science by Brenda Leady” (Leady 2017). We conducted an experiment of 8 different tests, 4 of the different classifications of pH, and 4 different…
