Peroxidase Enzyme Lab Report

In this lab the peroxidase enzyme is tested in a dormant avocado seed as well as an avocado seed undergoing the process of germination. A gas pressure will be used to test the seeds and see if the peroxidase enzyme is present in either of the seeds. A catalyst is very similar to track spikes. Spikes increase a runner’s speed, as a catalyst speeds up the chemical reaction time in a plant. Neither the catalyst nor shoes are changed in these actions. Enzymes are macromolecules that act like catalysts. A catalyst will lower the activation energy within a seed, which will allow the reaction to go quicker. An avocado seed is used in this experiment. For this type of seed to start the process of germination, the favorable climate is typically very warm. If someone was to plant an avocado seed and see the quickest results, they should place the seed in the sun. Along with waiting a few days between watering the seed, allowing the soil to dry out. For the seed to germinate properly, the bottom half of the seed will be emerged into water. Once the top of the seed becomes dry it will crack and the exterior brown skin will come …show more content…
A dormant avocado seed and an avocado seed in the process of germinating will each be tested, using a gas pressure. This tool will record if the peroxidase enzyme is present in either of the seeds. The seed undergoing germination will have awakened enzymes however the dormant seed will have un-hydrated enzymes. Depending on the amount of gas released from each seed will determine how much catalyst activity is going on in the seed. The independent variable is the amount of time that the seed will be tested for gas. The dependent variable is the gas pressure and how much gas is released from each seed. The peroxidase enzyme catalyzes the change form hydrogen peroxide into water and oxygen gas. It’s safe to assume that the dormant seed will not produce as much gas as the awakened seed
