An enzyme can be denatured (unfolded) by extreme heat, pH, or ionic concentration. If this happens
the enzyme will no longer be functional because the shape of the active site will be destroyed
In this exercise you will study the enzyme catalase, which speeds up the breakdown of hydrogen
peroxide, H202, (a common waste product of cellular metabolism) into water and oxygen
