problems about experiment
i need to study the effect of con.c of substrate on the enzyme reaction
the potato tubes are the sustrate
and the H2O2 are the enzyme
WHY THE POTATO SHOULD BE FRESHLY CUT
AND PUT IN WATER BEFORE DIRECTLY REACTING WITH H2O2??

If you cut a potato and leave it in air, the cut surface will dry up and form a kind of crust, protecting the tissues inside from further losing water to the surroundings. It will then be difficult for the H2O2 in the solution to access the substrate.
