Amy Rice BSC 2010L 10/09/08 Homework Assignment #5 Enzymes (Lab 5) A. Hypotheses 1. For the first experiment, our hypothesis was that enzymatic activity would increase with increasing temperature, up to 40 ° C, and then be lowest at 100 ° C. The results from our experiment supported our hypothesis; the data showed that enzymatic activity was greatest at 40 ° C, decreasing steadily with decreasing temperature, and almost non-existent at 100 ° C. 2. For the second experiment, our hypothesis was that enzymatic activity would increase as the pH becomes closer to neutral (7.0) from both sides (either acidic or basic), and would be the lowest at extreme pH values (very acidic or basic). This hypothesis was supported by the experiment; enzymatic activity was the greatest for solutions with a near-neutral pH (ranging from tap water with a pH of 6.71 to Sodium Bicarbonate with a pH of 8.02). Enzymatic activity was the lowest in solutions that had extremely low pH values (Lemon Juice with a pH of 2.28 and Sprite with
