1. Agenda 1/9 Enzyme Lab Data Collection
Enzyme lab analysis and lab posters
Turn in: Video notes
Homework: Properties of water video and notes

2. Catalase
Catalase is an enzyme that breaks down hydrogen peroxide into water and oxygen
Hydrogen peroxide is damaging to cells, so all living things possess catalase to break down hydrogen peroxide
What happens when you put hydrogen peroxide on a cut?
What is going on chemically?
Why would Ms. Poole not use hydrogen peroxide?

3. Catalase

4. Lab Objectives
Using activated yeast (as our catalase source) you will determine how various environmental factors affect enzyme function
You must complete multiple trials of your control and experimental groups
To get quantitative data easily, we will use small discs of paper soaked in catalase solution
As the disc rises up, what is happening?
How does this tell us anything about the rate of reaction?
