hydrogen peroxide

name the products in this reaction
2 water and oxygen

name the enzyme in this reaction
in the experiments, how do you know if a reaction had taken place?
if bubbling occured
What was the source of the enzyme you used in the experiments?
After the reaction was completed, what was left over in the test tube?
During the reaction what gas was released in the bubbles?
what happen to an enzyme when it is denatured?
becomes inactive
What temperature conditions denature most enzymes very hot or very cold temp?
very hot
Do changes in Ph denature enzymes?
reactions take place under what conditions?
if theres a substrate, catalase, and proper Ph
Tube with hydrogen peroxide and catalase is there a reaction?
tube with water and hydrogen peroxide is there a reaction? if no why not?
no-not correct substrate
tube with catalase and sucrose is there a reaction? if no why not?
no-wrong enzyme
What is the proper Ph for a reaction?
What is a ph lower than 7?
too acidic
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 the breakdown of hydrogen peroxide by catalase an endorgonic or exorgonic reaction? how did you prove this in lab?
exorgonic reaction, felt bottom of test tube
is catalase reusable?
