Homework #1

1. Go outside for a hike/walk/run and think about the microbes all around you. When you get home, look up 2 specific microbes that may have been in the soil, water or air. Describe some of their characteristics and what kingdom and domain they belong to.

2. Make a list of the 5 kingdoms we went over in lecture. Please state whether each kingdom is made up of prokaryotic or eukaryotic cells, and if those cells are multicellular, unicellular or both. To familiarize yourself with free-living versus parasitic organisms, please look up on the internet or in your textbook an example of a free-living (non-pathogenic) organism and a parasitic (pathogenic) organism from the Fungi and Protista Kingdoms.

3. Please describe how the debate over spontaneous generation of life was settled. In your description, include the main experiments that were conducted, what the results were and what theory they supported.

4. Please draw a typical bacterial cell. (Draw it, don’t copy and paste a picture) List the main structures of the cell and their functions. (at least 6) Then highlight where you would find the four biomolecules of life in the bacterial cell. For example, what structures would they be in, if in a structure, or what area of the cell. Then describe the function of those biomolecules in the cell.

5. In a eukaryotic cell there are membrane bound organelles. Please list at least 5 of these and their functions.

6. Bacteria and animal cells can both move. What do animal cells use to move with and what do bacterial cells use? Are they different structurally?

7. In cellular respiration, a typical bacterial cell produces 38 ATP. How many ATP molecules are produced during glycolysis, Krebs cycle and the Electron transport chain? What is chemiosmosis and why is most of the ATP produced during this process as compared to the ATP produced during glycolysis and the Krebs cycle?
