Abstract: This lab tests how temperature and pH affect how enzymes will function. The lab showed that temperature will denature an enzyme when past its optimal working temperature and won’t denature in cold temperatures‚ but have slowed molecular activity. pH will also have an affect on an enzymes efficiency‚ when out of optimal pH the enzyme will not function as it is supposed to and if to far out of the optimal pH the enzyme will change shape and no longer work. Enzymes also showed to be reusable

pH and Microbial Growth Introduction: Each organism has an optimum environment for growth‚ which includes pH level. Organisms that grow at near neutral pH levels are called neutrophiles. Those that grow best in acidic pH values are called acidophiles. Others‚ yet‚ grow best in alkaline pH values and are called alkaliphiles. In this lab‚ each group was assigned an organism‚ which was then used to inoculate 6 different pH levels. Materials and Methods: Followed lab procedure 29‚ “pH and

The Effects of pH on Slime Mold Dg Nicole Harris BIOL181 – 059 1 December 2011 The theory that slime mold is attracted to acidic solutions was examined by the slime mold‚ Dg. Dg’s preference of pH was examined by using a variety of pH solutions in a petri dish. The data suggests that the growth of fruiting bodies observed in pH 9 was comparable to that of pH 4.
