1. An investigation was performed to determine the rate of oxygen released from the decomposition (breakdown) of hydrogen peroxide by the human enzyme catalase. The investigation was performed at two different temperatures; the data is presented in the table below. Normal human body temperature is 37 ⁰C. The graph shows the results. Which statement about the enzyme is supported by the graph? *Catalase is an enzyme made up of many polypeptide chains
*Catalase decomposes hydrogen peroxide over time
*Catalase is a human enzyme
*Catalase becomes less effective in temperatures below 37 ⁰C.
