2,835 words... ial's and Methods The first experiment involved examining the effect of temperature on aerobic respiration of germinated pea seeds. The students testing the effect of temperature, will be divided into two groups. The first group is Student Pair A. They will test the effect of 10 C, 20 C and 30 C temperatures on pea respiration rate. The second group is Student Pair B. They will test the effect of 40 C and 70 C temperatures on pea respiration rate. For both groups, the first procedure calls f...

1,993 wordsEffects of Temperature, pH, and Gelatin on Bromelain Introduction Bromelain is an organic catalyst that speeds up the rate of chemical reactions. Bromelain is used in this experiment to catalyze the break down of proteins and is called a proteolytic enzyme. Enzymes enable reactions to occur at a lower temperature and energy levels. This allows many reactions to occur inside living organisms that would otherwise have been impossible to take place. This enzyme is found in fruits, leaves, and stems...
