Substrate Concentration Lab Report
When comparing the three different Substrate Concentrations (3%, 1% and 0.3%) as which one was the fastest to react, I hypothesized that the reaction would occur the fastest with the 3% hydrogen peroxide (the highest amount of concentration) because the higher the concentration the more faster the reaction occurs and helps produce or break up the enzyme. After testing all three of my substrate concentrations with 10 trials each, my data showed (first graph) that the 3% substrate concentration had the fastest average rate at 0.19 of distance and time occurring and my second data chart (table chart) showed an estimate time of 15-25 seconds. The second highest average rate of the reaction was at 0.08 of distance and time occurring and the estimated reaction time was between 25-50 seconds.

The lowest average rate was 0.03 in time and distance and showed an estimate time of 50 seconds to 2 minutes.
Based on the data I collected, my hypothesis was correct because the fastest reaction was the highest concentration (3%) and appeared to act faster than the other concentrations. My data shows that the highest concentration is the fastest to react and is best for repairing or breaking down. The factors that affected the enzyme was the different concentrations used such as the 3%, 1% and 0.3%. This shows that enzymes work best in faster concentrations and can easily break down or build up things much faster which leads to a better system. This is important to know because the more we have faster concentrations in our body, the more easily are bodies can break down and build up products in our body. This applies to homeostasis because we need to keep our body at a certain temperature to be able to function and keep the enzymes going and helping the body. If we have a over-heated body, we can possibly kill the enzyme and it will be very hard for our body to function. If our body is very cold, we could possibly freeze or slow down the enzyme process which leads up to body
failure.
The procedures that may have affected my results was how I dipped my hole punched dots into the potato extract. I could’ve left the hole punch dot inside the potato extract for a couple seconds longer to really see the effect of how long it would take for the reaction to occur. Another thing I could’ve done differently to get better results would be recording the lab, to double check if I saw the dot accurately rise to the top instead of being impatient and seeing it barely rise up to the top. The further experiments that I would like to try out are placing the experiment in different temperature rooms such as a very hot environment or very cold environment.
