Catalase liver and potato lab

Discussion: Upon conducting the experiment and carefully observing, there was no reaction when sand was added into the hydrogen peroxide H2O2 because it contained no enzyme. Enzymes have optimum temperature where they can carry out their activity.

The results that were yield when raw liver was placed in the first test tube is that there was a fast reaction, it was super bubbly, huge bubbles 12 cm tall and it had a tepid temperature.

Note 3. In the third test tube which had the crushed potato, white foam also appeared on top 1 inch tall and even more bubbly solution. Blend on high speed, pulsing when necessary, until the liver is smooth and no chunks are present.

I also thank my lab partner, Mario Tuyul, for his co- operation. To the blended liver drop, add one drop of hydrogen peroxide. Hydrogen peroxide can be broken down by manganese dioxide because it has catalytic properties. Consequently, when exposed to hydrogen peroxide the liver should have produced more bubbles oxygen gasand at a faster rate, when it was untreated than when exposed to vinegar or baking soda.

Explain why there is a difference in the rates of reaction between the liver and the potato The Effect of Hydrogen Peroxide on Liver: Hypothesis, Apparatus, Method Liver contains more of the enzyme catalase, which breaks down hydrogen peroxide.

The reaction is exothermic. The bubbling reaction you see is the metabolic process of decomposition, described earlier.

Several factors affect the rate at which enzymatic reactions precede- temperature, pH, enzyme concentration, substrate concentration and the presence of any inhibitors or activators. Huge bubbles were produced and there was a very apparent tepid temperature.
