Sam is studying the effects of temperature change on a specific enzyme, catalase. this enzyme is found in cells and break down hydrogen peroxide. as part of her project, she measures the rate at which hydrogen peroxide is broken down by catalase at 20, 25, 30, and 35oc. which question best describes sam's science research project?
