|
|
What temperature conditions denature most enzymes very hot or very cold temp?
|
very hot

Do changes in Ph denature enzymes?
|
yes
|
|
|
reactions take place under what conditions?
|
if theres a substrate, catalase, and proper Ph
|
|
|
Tube with hydrogen peroxide and catalase is there a reaction?
|
yes
|
|
|
tube with water and hydrogen peroxide is there a reaction? if no why not?
|
no-not correct substrate

|
|
What is a ph higher than 7?
|
too basic
|
|
|
presented with two test tubes:One of the tubes has more catalase than the other, if the same amount of hydrogen peroxide is simultaneously added to both predict what will happen?
|
one will have a bigger reaction
|
|
|
Does liver contain catalase? If yes, how did you prove this in lab?
|
took liver out and put hydrogen peroxide back in tube

is catalase reusable?
|
yes
