This lab report examines how varying temperature levels affect the activity of the enzyme catalase. The research aims to determine whether higher temperatures enhance or inhibit enzymatic function and measures the reaction rates under different thermal conditions. Background information includes enzyme structure-function relationships and previous studies indicating optimal temperature ranges for various enzymes. The hypothesis posits, “If temperature increases, then catalase activity will initially increase, because optimal heat enhances molecular motion until denaturation occurs.” Results are analyzed through data representation and examined for trends in enzyme efficiency.
