Students use enzymes in liver to breakdown hydrogen peroxide. The reaction is measured by the temperature changes.
Cells build up hydrogen peroxide during cellular reactions and it is harmful to the cells. The liver has an enzyme called catalase that breaks down hydrogen peroxide to carbon dioxide and water so it can be released from the cells. The heat released goes up rapidly, levels off, and then drops so it is easy for the students to calculate the changes.
