Vernier - Enzyme Action: Testing Catalase Activity

Activity Overview

Students will use an O2 Gas Sensor to measure the amount of O2 produced when H2O2 is broken down by the enzyme catalase at different concentrations, pH values, and temperatures. They will also measure the enzyme's initial reaction rates.
