Catalase Lab
The two purposes of this experiment were to see the effect of enzyme concentration on enzyme activity and to see the effect of temperature on enzyme activity. Enzymes are the most important part of living cells. Cells can't work or carry out there jobs without them. Enzymes act like catalysts in living cells. Catalysts speed up chemical reactions but remain unchanged by it. Enzymes are made of protein. Enzymes are sometimes called enzyme catalysts. There is a specific enzyme for every chemical reaction in the body. The chemicals that enzymes react in are called substrates. An enzyme performs its effect by combining temporarily with its substrate. As a result, a substrate becomes more reactive. The rate of the formation of products increases.Catalase is present in most cells and high concentrations are foun
I would also provide a holder for the graduated cylinder because it got heavy and was sometimes lifted above the water accidentally. I predict that the increase in temperature will effect the enzyme activity by making it higher because our bodies function better at a high temperature so it makes sense that the enzymes that are in us would. I thought that it was strange how that particular line was higher than the 1 disk, 3 disks, and 4 disks group. Hydrogen peroxide is formed as a by-product of cellular respiration in cells but water is the most common one. " In summary, the results given prove my hypotheses correct. We saw that enzyme activity is lower at lower temperatures but I would like to see if they get higher or lower at higher temperatures. I also predict that more concentration of enzymes will result in higher enzyme activity. I think that maybe the filters were soaked for too long and that was what made that group's numbers skyrocket. On the temperature chart, you will see that as the temperature went up, so did the enzyme activity. In conclusion, this lab went well and we accomplished the purpose and got the results that we were looking for. I f my prediction is correct, I will have proved that enzyme activity is higher at higher temperatures.
