Liver Enzyme Demonstration
Part 1: Raw Liver
1. Write the chemical equation for the reaction in the demonstration. Label the reactants
and the products.
2. After observing the reaction, what evidence did you observe that a chemical reaction took
place.
3. Record readings on the temperature probe before and during the reaction. Is this reaction
endothermic or exothermic?
4. How could we measure how fast this reaction occurring?
5. Draw a model diagram of this reaction. Label Substrate, Enzyme, and Products.
Part 2: Cooked Liver
1. What do you observe in this reaction? Is a reaction taking place? How can you tell?
2. Describe and changes in temperature during the course of the reaction.
3. Draw a model diagram of this reaction and explain what is different from using the raw
liver enzymes.
