Cell walls are found in which of the following (select all that apply):
- Algae
- Bacteria
- Mammalian cells
- Plants
- Fungi
- Algae
- Bacteria
- Plants
- Fungi
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
, 2
- To produce energy: Mitochondria are considered the power plant of the cell, as it
produces ATP
True or False: All multicellular microorganisms classified as Animalia are
autotrophic
False - they are heterotrophic
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
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
True or False: The beta-oxidation pathway catabolizes the fatty acid chains of lipids
True
True or False: Plants, algae and bacteria all contain chloroplasts
False - Chloroplasts are specific to algae and plants only
, 3
The process of photophosphorylation produces which of the following: Select all
that apply.
- ATP
- Glyceraidenhyde 3-phosphate
- NADPH
- H20
- C02
- ATP
- NADPH
Short Answer: What is one of the main functions of light reactions?
- to generate ATP via proton concentration gradient
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
True or False: Following the decolorization step of the Gram stain, Gram-negative
bacteria will appear colorless
True - even together, the LPS and thin peptidoglycan layer are unable to retain the
crystal violet dye during decolorization
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
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.
