Report Issue This contains 100% correct material for UMUC Biology 102/103 LAB04. However, this is an Answer Key, which means, you should put it in your own words. Here is a sample for the Pre lab questions answered:Lab 4: EnzymesANSWER KEYPre-Lab Questions1. How could you test to see if an enzyme was completely saturated during an experiment? (2 pts)To test this, you’d simply see if the reaction was still taking place. If the enzyme was completely depleted, the reaction could no longer occur.2. List three conditions that would alter the activity of an enzyme. Be specific with your explanation. (2 pts)Temperature, salinity, and acidity are three conditions that affect enzyme activity. Specific examples include:Adding a salt packet to an enzyme would alter its activity–salt ions are often necessary for optimal enzyme activity, so too much or too little salt will slow down the rate. Enzyme activity increases with increasing temperature, until it becomes hot enough to denature the protein (enzymes are proteins), then the activity would cease.Enzymes have an optimum pH where they function the best. Higher or lower pH than the optimum slows the rate of activity. 3. Take a look around your house and identify household products that work by means of an enzyme. Name the products, and indicate how you know they work with an enzyme. (2 pts)
