You are studying enzymes in biology class. hydrogen peroxide (h2o2) is produced as a byproduct of respiration. hydrogen peroxide is harmful to cells and must be continually broken down. catalase is an enzyme found in living cells that speeds up the breakdown of hydrogen peroxide into water and oxygen (2 h2o2 → 2 h2o + o2). you are working with your lab group to investigate what factors influence the rate of the peroxide reaction. your lab group is provided with liver samples as a source of catalase, as well as 3% hydrogen peroxide. you decide to investigate if adding more enzyme will cause the reaction to proceed faster. you set out to prove the hypothesis: if more catalase is provided, then the rate of the peroxide reaction will be faster. what would be a good choice for your independent variable? a) 3,5, and 10 g samples of liver b) measuring the amount of oxygen produced c) 1%, 3%, and 10% concentrations of hydrogen peroxide d) 10 ml, 20 ml, and 30 ml volumes of hydrogen peroxide
