1. Rods.
2.
a. Anabolism. The process of using the energy and simple building
blocks to make new macromolecules for the cell
b. Catabolism. The process of breaking down macromolecules into
their smaller component parts.
c. Chemolithotrophy. Converting inorganic chemical energy such
as hydrogen gas or sulfur into ATP.
d. Fermentation. The conversion of organic chemical energy, such
as organic waste or sugars, into ATP.
e. Photosynthesis. The conversion of light energy into ATP.
f. Respiration. The conversion of organic chemical energy, such
as organic waste or sugars, into ATP.
3. What are the primary
producers in a deep sea food chain? Chemolithotrophic bacteria.
What do these organisms use for an energy source? Oxidation of
inorganic chemicals.
4. To get energy for their
growth.
5. Lag: Cells are synthesizing DNA and enzymes. Log: Maximum growth rate under conditions provided. Stationary: The number of cells dying equals the number of cells dividing. Death: The number of cells dying is greater than the number that are dividing.
6. Sedimentation: Separation
of solids from water. Activated sludge: Microbial digestion of
suspended and dissolved organic compounds in the water. Anaerobic
digester: : Microbial digestion of organic compounds. Activated
sludge requires O2.
#1-Water goes to receiving water such as a river or ocean; or
onto land for irrigation.
#2-Solids go to a dump or to agricultural land.
7. Both industries use
the same metabolic process, fermentation.
8. A different strain of yeast could produce an off-taste. Acetobacter oxidizes ethyl alcohol to acetic acid (vinegar).
