Straighterline Microbiology QuestionsAnd Answers With Verified Solutions
Already Passed!!!
Louis Pasteur - ANSWER✔✔ Disproved spontaneous generation with his flask
experiment. Invented pasteurization, or heating things to destroy
microorganisms.
Jablot, Redi, Schultz, and Schwann - ANSWER✔✔ Conducted experiments
supporting the hypothesis of biogenesis.
Atom - ANSWER✔✔ Nucleus is made of protons and neutrons, outer shells filled
with protons. #electrons=#protons
Hydrogen bond - ANSWER✔✔ Weak, results from attractive forces between
molecules with polar covalent bonds. Not technically a bond, but super
important.
Acidic - ANSWER✔✔ low Ph, H+
Basic/Alkaline - ANSWER✔✔ high Ph, OH-
Carbohydrates - ANSWER✔✔ Sugars and polysaccharides. Serve as food storage
(starch) and contribute to cell structural support (cellulose).
Lipids - ANSWER✔✔ Fats, Phospholipids, and Waxes. Hydrophobic. Chill in the cell
membrane reinforcing cell structure.
,Poteins - ANSWER✔✔ Enzymes, antibodies. Four stages in formation. Made of
amino acids
Nucleic Acid - ANSWER✔✔ Cell programmers. Adenine, Guanine, Thymine,
Cytosine, and Uracil.
DNA - ANSWER✔✔ Double stranded. Nitrogenous base, pentose sugar
(deoxyribose) and nucleic acids (A-T, C-G)
RNA - ANSWER✔✔ Single stranded. Nitrogenous base, pentose sugar (ribose), and
nucleic acid (A-U, C-G)
ATP - ANSWER✔✔ Adenosine triphosphate. Adenine, ribose (pentose sugar), and
three phosphates (PO4). "currency of the cell"
Five I's of Microbe Culturing - ANSWER✔✔ Innoculation, incubation, isolation,

Pathway of magnification - ANSWER✔✔ Light source-->condenser lens (focuses
light)-->specimen-->objective lens (enlarged, real image)-->ocular lens (mirrored/
"virtual" image)-->eye
Bacteria - ANSWER✔✔ cell membrane, cytoplasm, chromosome(s), usually cell
wall (with peptidoglycan), cytoskeleton, glycolax.
, monotrichous flagella - ANSWER✔✔ A subtype of polar flagella. A single flagella
Lopotrichous flagella **lo·phot·ri·chous - ANSWER✔✔ Subtype of polar flagella,
tufts of flagella emerging at the same site.
Peritrichous Flagella **pe·rit·ri·chous** - ANSWER✔✔ flagella randomly
dispersed all over cell
Periplasmic Flagella/Axial Filaments - ANSWER✔✔ Enclosed in the space between
cell wall and cell membrane. Twist to move the cell? It's all very confusing.
Gram stain - ANSWER✔✔ crystal violet, iodine, alcohol, safranin. G+ has thick
peptidoglycan layer and stains 'blue', G- has inner and outer membrane and stains
'red'. They don't really, it's more like purple and pink.
Mycoplasmas - ANSWER✔✔ naturally lack a cell wall
Lipopolysaccharides (LPS) - ANSWER✔✔ present in G- cell walls, sometimes
referred to as endotoxin because it stimulates shock reactions in human hosts.
Enzymes - ANSWER✔✔ Catalyst macromolecules. Reusable. Provides reaction site
for substrates.
Protozoa - ANSWER✔✔ Generally microscopic single celled prokaryotes.
Reproduce asexually and sexually during different parts of their life cycle.
