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

The reason collision theory relates to this experiment is due to the fact that the catalyst creates a higher activation energy and this causes more collisions‚ which increases the reaction rate. In the second experiment‚ the Alka Seltzer tablet was
