Which of the following are considered Protista? Select all that apply:
- Bacteria
- Amoeba
- Algae
- Yeast - (answer)- Amoeba
- Algae
True or False: A defining characteristic of Protista is the inability of colonies to form tissue
layers - (answer)True
The function of the ribosome is (select all that apply):
- To produce energy (ATP)
- Lipid Synthesis
- Protein Synthesis
- Waste disposal via hydrolytic enzymes - (answer)- Protein synthesis: ribosomes are located in
the cytoplasm of prokaryotic cells and in the ER of eukaryotic cells.
Cell walls are found in which of the following (select all that apply):
- Algae
- Bacteria
- Mammalian cells
- Plants
- Fungi - (answer)- 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 - (answer)- 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 -
(answer)False - they are heterotrophic
How many ATP does the tricarboxylic acid (TCA) cycle produce per pyruvate?
- 2 ATP
- 34 ATP
- 4 ATP
- 1 ATP - (answer)- 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 - (answer)- Lactose
- Carbohydrates
, - Lipids
True or False: The beta-oxidation pathway catabolizes the fatty acid chains of lipids -
(answer)True
True or False: Plants, algae and bacteria all contain chloroplasts - (answer)False - Chloroplasts
are specific to algae and plants only
The process of photophosphorylation produces which of the following: Select all that apply.
- ATP
- Glyceraidenhyde 3-phosphate
- NADPH
- H20
- C02 - (answer)- ATP
- NADPH
Short Answer: What is one of the main functions of light reactions? - (answer)- to generate ATP
via proton concentration gradient
True or False: The Calvin cycle must occur in the absence of light - (answer)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 - (answer)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? - (answer)False - both heat and chemical strategies will kill the
cell, making motility observations impossible
