Enzyme hydrogen peroxide potato lab. I am not so sure of my controlled group and experimental group. Some potato pieces were boiled n then hydrogen peroxide was added and the other potatoes were kept at room temperature. I attached the procedure. Please help and thank you in advance ?

Hypothesis and explanation:
As the temperature increases, the performance of the catalase on hydrogen peroxide will decrease. This is because
high temperatures cause enzymes to denature (destroy or alter its qualities so it won't work properly).
1. Dice about 2 tablespoons of raw potato into small pieces. Boil 1 tablespoon of diced potatoes for 10
minutes. Leave the remaining tablespoon of diced potato at room temperature.
2. Place equal amounts of diced potato prepared at different temperatures (boiled and room T) into 2 small
cups or bowls.
3. Measure 1 tablespoon of hydrogen peroxide and quickly add to each treatment and observe for 1 minute.
Bubble formation is evidence of O2 production and indicates that the enzyme-catalyzed reaction is
C
occurring. Take a picture of your experimental setup al insert here:
