1.What is an enzyme? What type of macromolecule are enzymes most often composed of? Using a chemical equation explain enzyme reactions? Using a diagram explain how enzymes work by lowering activation energy.
2.Why do we attempt prevent the growth of some or all microbes-list several reasons why this might be valuable or necessary? Discuss three methods of physical control of microbes. List 5 different categories of chemical agents used in microbial control and discuss each. What are antibiotics? How have we created massive problems for treatment because of the rise of resistance?
3.What is the difference between aerobic and anaerobic respiration? How is fermentation different from both of them? Discuss two common fermentations that we use to make everyday useful products.

1. In the unique bacterial enzyme laboratory (e.g., DNAse, Starch, NO3 tests) there were a number of tests that required the addition of some reagent after the cells had grown. List and describe all tests with reagents added after growth. Why do we have to add these reagents after incubation, when in many other tests the indicators are incorporated into the medium? Be sure that you know how to score a reaction positive or negative, and what each of those...
