Hydrogen peroxide (H₂O2) is naturally formed in living organisms; however, it is very harmful and is broken down immediately by catalase into water and oxygen. This reaction occurs in the peroxisome, an organelle present in both plant and animal cells. Design an experiment to determine which of the following three food samples contains the highest concentration of catalase: dried potato, ground meat, and fresh ground leaves. Outline your procedure step-by- step. Independent Variables: Dependent Variables: Control Variables: Procedure:
