Overview: Biology?s Most Exciting Era Biology is the scientific study of life. You are starting your study of biology during its most exciting era. The largest and best-equipped community of scientists in history is beginning to solve problems that once seemed unsolvable. Biology is an ongoing inquiry about the nature of life. Biologists are moving closer to understanding: How a single cell develops into an adult animal or plant. How plants convert solar energy into the chemical energy of food. How the human mind works. How living things interact in biological communities. How the diversity of life evolved from the first microbes.

Katie Hallstead Mrs. Legary AP Biology p. 0 November 1, 2012 AP Biology Lab 2: Enzyme Catalysis Abstract: This experiment tested the effects of extreme temperatures on catalase activity, the reaction of catalase and hydrogen peroxide, and the rates of decomposition of hydrogen peroxide by enzyme catalysis. We used titration and baseline techniques to drop the potassium permanganate into the hydrogen peroxide and sulfuric acid, and we counted how many drops it took for the solution to permanently turn purple. We recorded how long it took and how much potassium permanganate was used. We recorded our results of how long it took for the solution to turn purple and how much potassium permanganate was used. Problem: What is the baseline amount of hydrogen peroxide in a 1.5% solution?
