A. Warm-Up: Response Page….How does the length of the food tube compare to a person’s height?
B. Enzyme Lab… Today we experimented to determine which has more of the enzyme catalase..liver or potato. So, what did you find out?
If you did not finish..here is some Data you can use. How does your compare?
Cubed Liver: diameter – 16.5 cm, reaction time 211 sec, rate: 4
Observations: It was fizzy, warm, and the liver floated.
Cubed potato: diameter – 13.5 cm, reaction time 360sec, rate: 3
Observations: It fizzed, floated, but was not warm.
Mashed liver: diameter – 17 cm, reaction time 97sec, rate 5
Observations: It was warm, very bubbly, and explosive.
Mashed potato: diameter – 17cm, reaction time 360 sec, rate 3
Observations: It was slightly warm, floated, and bubbled.
