The purpose of this experiment was to see if there would be any enzymatic activity in catalase, which is found in potatoes. The way my partner and I did the experiment was very simple: we put the filter paper filled with catalase concentration into five sets of hydrogen peroxide. We found that the higher the hydrogen peroxide concentration, the faster it would take the filter paper to reach the top, and the lower or no hydrogen peroxide concentration level, the slower it would go to reach the top. the summit. The results of our experiment showed us that the higher or lower level of hydrogen peroxide would determine how long it would take to float to the top. Introduction: According to the textbook Biology Life on Earth with Physiology 10th edition, enzymes are biological catalysts that are made of proteins, and they accelerate the rate of a specific biological reaction. (Audsirk, Audsirk and Byers 100-105) and chemical reaction rates increase without changing the chemical balance between reactants and products. (Cooper, 2000). All enzymes have a pocket, called the active site, into which reactants, called substrates, could enter. (Audsirk, Audsirk, and Byers 100-105) Enzymes regulate exergonic and endergonic reactions, and enzymes are found in almost all cells (Audsirk, Audsirk, and Byers 100-105). Enzymes are regulated by three different regulations; Regulation of allosteric enzymes, competitive inhibition and competitive inhibition. (Audsirk, Audsirk and Byers 100-105). In the regulation of allosteric enzymes, an inhibited molecule causes an active site to change shape. In competitive inhibition, the enzyme and substrate bind normally, and in non-competitive inhibition, a substrate imposter...... middle of paper ...... first try, it took the filter paper 22 seconds filled with catalase liquid to reach the top of the test tube, and for our second trial, it took 25 seconds for the filter paper filled with catalase liquid to reach the top of the test tube. This pH had a weak reaction because it had the same pH as baking soda. Overall, for the experiments, the higher the doses of hydrogen peroxide, the faster the reaction, and the lower or no dose of hydrogen peroxide, the slower the reaction. Results: Our results were about the same each time, but some were higher than some or some. had no reaction. Our first variable had an average time of 48 seconds to float, with the second maximum being 115.9 seconds and the second minimum being 0 seconds. It had a faster rise time with 3% H2O2 due to its high enzyme concentration, and it took longer, if at all, due to the lower H2O content.2.
