Purpose The purpose of performing this lab is to compare the action of catalase to a non-protein catalyst under different conditions. Hypothesis In section A‚ I hypothesize that the sand will have no reaction but the MnO2 will produce a gas or start to foam up. In section B‚ I suspect that the liver may start to show signs of deformation
