Enzyme Activity Lab Abstract In the investigation, a catalase and an enzyme whose occurrence is widespread in cells, particularly in liver cells was used. The catalase from a fresh calf liver was used. In this lab, catalase and H2O2 were combined under different substrate concentrations 6%, 4%, 2%, 1% and 0.5% with two drops of diluted detergent. Measurements of the volume of O2 released during these reactions were recorded to determine the rate of reaction. The reaction rates of …showed first 75 words of 1007 total…

When the substrate concentration is lower the reaction rate is slower. References Books Starr, Cecie. Taggart, Ralph. The Unity and Diversity of life.
