2. True or False: A defining characteristic of Protista is the inability
of colonies to form tissue layers: True
3. The function of the ribosome is (select all that apply):
- To produce energy (ATP)
- Lipid Synthesis

-Bacteria
-Plants
-Fungi
5. The function of the mitochondria is (select all that apply):
- To produce energy
- Protein synthesis
- waste disposal via hydrolytic enzymes
- Protein modification and distribution
- lipid synthesis: - To produce energy: Mitochondria are considered the power plant of the cell,
as it produces ATP

6. True or False: All multicellular microorganisms classified as
Animalia are autotrophic: False - they are heterotrophic
7. How many ATP does the tricarboxylic acid (TCA) cycle produce per
pyruvate?
- 2 ATP
- 34 ATP
- 4 ATP
- 1 ATP: - 1 ATP: The TCA produces only 1 ATP per pyruvate
8. In the absence of glucose, which of the following can be used as
alternative energy sources? Select all that apply:
- Nucleic Acids
- Lactose
- Carbohydraes
- Lipids: - Lactose
-Carbohydrates
-Lipids
9. True or False: The beta-oxidation pathway catabolizes the fatty
acid chains of lipids: True
10. True or False: Plants, algae and bacteria all contain
chloroplasts: False - Chloro-plasts are specific to algae and plants only
11. The process of photophosphorylation produces which of
the following: Select all that apply.
- ATP
- Glyceraidenhyde 3-phosphate
- NADPH
- H20
- C02: - ATP
-NADPH
12. Short Answer: What is one of the main functions of light
reactions?: - to generate ATP via proton concentration gradient

13. True or False: The Calvin cycle must occur in the absence of light:
False - the term "dark reactions" (also known as the Calvin cycle) simply denotes the second stage
in photosynthesis - dark reactions do not actually require darkness in order to occur
14. True or False: Following the decolorization step of the Gram
stain,
Gram-negative bacteria will appear colorless: True - even together, the LPS and
thin pepti-doglycan layer are unable to retain the crystal violet dye during decolorization
15. True or False: if you wish to study motility of an organism
you cannot heat fix, but you can chemically fix the specimen?: False - both heat
and chemical strategies will kill the cell, making motility observations impossible
16. Short Answer: You want to observe the size and shape of a cell.
What is the easiest staining technique that you could perform? Name
at least one dye you would use during this process.: Simple stain - the dyes you
could use could be:
-Methylene Blue
-Crystal Violet
-Safranin
-Fuschin
17. Short Answer: You suspect a patient may have TB. Once a
sample has been obtained, it is sent off to the lab for an acid-fast
stain. If the patient were infected with TB, describe what you would
expect to see on the stained slide: If the patient was infected with TB, I would expect
to see red cells on blue background of the stained slide (which is TB-)
18. True or False: If a patient is suspected of having malaria, a
Giemsa stain would be an appropriate differential test t perform: True -
Giemsa stains are often used in clinical settings to aid in the diagnosis of blood parasites
19. Short Answer: Identify what type of electron sed to
microscope was u ture the following image and explain your cap-
choice: Transmission Electron M This is due to the subcellular components icroscope
being visible at 20nm. Further, this images lack the app "outside" shell (TEM).
20. True of False: The purpose of a quadrant streak is to produce
individual colonies of a bacterial population: True - the purpose of the quadrant streak
