BIOD171 Portage Microbiology Final Exam
Questions With Correct Answers
1. What various functions do proteins have in a cell: Proteins may facilitate
| | | | | | | | | | |
themovement of materials in or out of a cell.
| | | | | | | | | |
Some can act as enzymes that catalyze, or speed up, biochemical processes. Others
| | | | | | | | | | | |
play a structural role while other proteins, such as filaments, enable move-ment.
| | | | | | | | | | | | |
2. What are the main morphologies of bacteria?: Bacteria can be described
| | | | | | | | | |
ascoccus (round/spherical),
| | |
bacillus (rod), |
vibrio (curved
| |
rod)
|
spirillum (spiral/corkscrew). |
3. What are the 4 main classifications of Eukarya: Animalia, Plantae, Fungi
| | | | | | | | | |
orProtista
| |
4. What are the primary cellular organelles described in this module? Be sureto
| | | | | | | | | | | |
know the roles of each.: Ribosomes (protein synthesis)
| | | | | | | |
ER (site of protein synthesis)
| | | |
1 |/ |9
,Golgi (protein modification and distribution) lysosomes (waste
| | | | | |
disposal),mitochondria (ATP generation)
| | | |
chloroplasts (plants only; site of photosynthesis). | | | | |
5. True or False: Enzymes are polysaccharides that catalyze chemical reac-
| | | | | | | | |
tions.: False. Enzymes are proteins
| | | | |
6. What are usually metal ions known to assists enzyme during the
| | | | | | | | | |
catalysisreaction?: Cofactors
| | |
7. Define catabolism: the breakdown of complex molecules in living
| | | | | | | |
organisms,release of energy
| | | |
8. Upon cellular injury,which metabolic process is involved during the growthand
| | | | | | | | | | |
repair phases of the cell?: The anabolic process would be active as it is involved in
| | | | | | | | | | | | | | | |
the building up of small complexes into larger complexes.
| | | | | | | | |
9. Describetheenergytransfer process relativetobothATP and ADP.: ATPhas the
| | | | | | | | | | | | |
energy (phosphate group) to donate while ADP can accept energy in the form of a
| | | | | | | | | | | | | | |
phosphate group.Thus, ATP can be reduced (ATP ’ADP + Pi) while ADP can bebuilt into
| | | | | | | | | | | | | | | | |
ATP (ADP + Pi ’ATP).
| | | | |
10. An organism that derives its energy (generates ATP) from photons of lightis
| | | | | | | | | | | |
called a
| | : Phototrophic microorganism.
| |
11. An organism that derives its energy by removing electrons from
| | | | | | | | |
2 |/ |9
, |elementalsulfur would be classified as a
| | | | | | ?: Lithotroph
|
12. A reactive intermediate would be present in which phosphorylation
| | | | | | | |
| process?: The chemical compound losing the phosphate group is referred to asthe
| | | | | | | | | | | |
| phosphorylated reactive intermediate. | |
13. What is the primary byproduct of theTCA cycle?: NADH and FADH2
| | | | | | | | | | |
