When in extreme temperatures, boiled, baked, or frozen then the enzymes would denature. The data we collected supported our hypothesis because the raw potato had 8.25 mm of foam more than the boiled potato with 3.25 mm, frozen with .25 mm, and baked with .5 mm.

  • Since our potato was raw, the catalase in the enzyme of the potato was not altered or damaged at all. If the potato were to be boiled or frozen, then the catalase would be damaged and would not cause a reaction as it had done with the raw potato. Our experiment had shown this reaction accurately. The ammonia however does not react with the ...

Explain why there is a difference in the rates of reaction between the liver and the potato. The liver contains more of the enzyme catalase, which breaks down hydrogen peroxide. The liver contains more because it detoxifies substances in the body. A larger amount of catalase lowers the activation energy, therefore speeds up the rate of reaction.i) how enzymes work, using amylase as an example. ii) what a "control" experiment tells you. iii) how to carry out 2 common food tests.
