What was the function of the enzyme in the reaction?
How did you know that the catalase enzymes in the liver were working?
What evidence did you see?
What was breaking down the hydrogen peroxide and making the oxygen bubbles?

In test tube 1 with no liver, were produced because .
In test tube 2 with raw liver, were produced because .
Which liver sample had enzymes that were denatured?
SELECT ALL THAT APPLY!!!
When a piece of liver is dropped into hydrogen peroxide, the peroxide bubbles vigorously.
What causes this reaction?
If the environment is too extreme, enzymes can be damaged under these conditions.
What condition affected the function of the enzyme in the lab?
Label the diagram below. Not all answers will be used.

The graphs show the reaction rate for an enzyme across a range of temperatures and pH.

Based on these data, this enzyme functions best at what temperature and pH?
Hydrogen peroxide is a dangerous toxin and therefore can be used to kill bacteria that have entered a wound.

Considering what you know about enzymes which of the following statements describes why it is safe to pour peroxide into a wound to disinfect it.
The liver helps protect the body by removing or changing harmful substances. One substance the body sometimes makes is hydrogen peroxide, which can damage cells if not handled quickly. The liver uses special proteins called enzymes to help with this process.
Why is the decrease in these important enzymes seen in diseases such as NAFLD and cirrhosis so dangerous for the human body?
Beta-Galactosidase is an enzyme that breaks down galactose (a sugar). Whenever galactose is removed from Fluorescein, the molecule glows.

Normally, a certain species of jellyfish glows bright green. However, a small population was moved from the ocean into an aquarium, where the salinity (pH) is lower and can no longer glow.
The jellyfish no longer glow because the enzyme due to .
In test tube 3 with cooked liver, were produced because .
In test tube 4 with pickled liver, were produced because .
The most bubbles were produced by the liver because this sample contained .
