Biologie practicum: Enzymen
Waterstofperoxide en katalase




1. Hypothese
Er wordt verwacht dat als we in een buisje aardappelen met waterstofperoxideoplossing
mengen dat dan de enzymen in de aardappelen er voor zullen zorgen dat de
waterstofperoxideoplossing scheidt in zuurstof en water en dat er in het buisje met het
water en de aardappelen geen reactie plaatsvindt.

2. Materiaal
 Aardappel
 Mes
 Frietsnijder
 2 reageerbuizen en een reageerbuis rek
 Waterstofperoxideoplossing (H2O2) van 3%
 Maatcilinder van 10 ml

3. Werkwijze
1. Snijd drie stukjes aardappel af van ongeveer 1 bij 1 cm met behulp van de frietsnijder
en het mesje.
2. Doe in beide reageerbuizen 5 ml Waterstofperoxideoplossing
3. Doe in 1 buisje de drie stukjes aardappel
4. Doe in het andere buisje water totdat de inhoud van beide buizen gelijk is.
5. Wacht nu enkele minuten tot je resultaat ziet
