Ch. 2 Answer Key
Sep 12, 2006 · Catalase catalyzes a reaction that releases oxygen gas. Bubbles of oxygen form around the filter-paper disk, lifting it to the surface of the liquid. The more active the enzyme, the more quickly bubbles suffi-cient to lift the disk are produced. 2.A possible stu-dent answer would be that temperature directly affected the catalase activity.

Effect of pH on Catalase Activity
faculty.pingry.k12.nj.usA stock solution of catalase enzyme solution was obtained 1. 40 mL of the enzyme solution was measured into eleven 50mL beakers that were labeled as follows: pH 2, pH 3, pH 4, pH 5, pH 6, pH 7, pH 8, pH 9, pH 10, pH 11, and pH 12. 10mL of a 1mol solution of each pH was added into each appropriate beaker.

Put 1 cm3 hydrogen peroxide solution in a test tube. 2. 3Add 1 cm of catalase solution. • Bubbles of oxygen are produced. • Bubbles cause foam to rise up the tube. 3. Measure the maximum height of the foam. Figure 4 shows the experiment. Figure 4
