Potato And Hydrogen Peroxide Experiment. In class a series of experiments were performed that pertained to the enzyme known as catalase which converts hydrogen peroxide into oxygen. Potato and Hydrogen Peroxide Enzyme Lab by Brittany Gotts. The chemical reaction which is the bubbling will not take place because boiling the potato would destroy the enzyme. The amount of substrate hydrogen peroxide will effect the potatoes because the more hydrogen peroxide that is placed on them the more the catalase will be effected making the reaction speed up.

Hydrogen peroxide is the by-product of respiration. Internet Biology Book Chapter on. Hydrogen peroxide is harmful and must be removed as soon as it is produced in the cell. Potato samples catalase source will be placed in a pH buffer solution before being exposed to the Hydrogen-peroxide substrate O2 production will then be measured in cm3 across a controlled period of time. This investigation looks at the rate of oxygen production by the catalase in pureed potato as the concentration of hydrogen peroxide varies. In the potato catalase experiment the hydrogen peroxide acted as the_ in the enzyme reaction catalyst b.

The experiment should take no more than 2030. Having a greater amount of substrate to work with allowed it to then make more bubbles in such a short time. From the data collected a common trend throughout the graph a positive correlation can be seen as the highest temperature produced 7 ml of oxygen gas whilst the lowest. In conclusion the raw potato contained the most catalase because the average percent change in mass of 98 was the greatest of the three cooking preparations. We used a potato and 3 diluted hydrogen peroxide in our experiment to mimic the reaction on an observable level. The reaction in the experiment.

This investigation looks at the rate of oxygen production by the catalase in pureed potato as the concentration of hydrogen peroxide varies. The hydrogen peroxide solution was kept in a glass beaker and therefore due to the time factor a higher percentage of the hydrogen peroxide would have broken down when performing the pH9 experiment than the pH5 experiment. In this conducted experiment the variable measured was the duration of the reaction on a raw sweet potato. The experiment will be conducted at a temperature of 25o as temperature has such a big effect on enzyme activity as shown below. Why does potato react with hydrogen peroxide.

From the data collected a common trend throughout the graph a positive correlation can be seen as the highest temperature produced 7 ml of oxygen gas whilst the lowest. The chemical equation for the decomposition of hydrogen peroxide is 2 H2O2 2 H2O O2. The baked potato contained the second most amount of catalase with its average percent change in mass of 51 barely surpassing the boiled potato with an average percent. Due to peroxide being toxic to the tissues of both plants and animals both possess the enzyme catalase which breaks into two non-toxic. Hydrogen peroxide is the by-product of respiration.

Hydrogen peroxide decomposes slowly in light to produce oxygen and water. In class a series of experiments were performed that pertained to the enzyme known as catalase which converts hydrogen peroxide into oxygen. If potatoes are used as a peroxidase in the hydrogen peroxide solution they will generate more oxygen than if apples are used because potatoes contain more catalase and when catalase is added to hydrogen peroxide there is an initial rapid evolution of oxygen. Answer 1 of 2. The baked potato contained the second most amount of catalase with its average percent change in mass of 51 barely surpassing the boiled potato with an average percent.

It had a greater reaction throughout all three trials in the potato and hydrogen peroxide experiment. We conducted the experiment so that we were able to have a control group utilizing water while we were able to change the variables with hydrogen peroxide ammonia and vinegar. We used a potato and 3 diluted hydrogen peroxide in our experiment to mimic the reaction on an observable level. The oxygen produced in 30 seconds is collected over water. In this practical students investigate the presence of enzymes in liver potato and celery by detecting the oxygen gas produced when hydrogen peroxide decomposes.
