UB MIC 401 EXAM 2 QUESTIONS AND VERIFIED
ANSWERS
p-aminobenzoic acid
folic acid
biotin
cobalamin (B12)
nicotinic acid
riboflavin
thiamine (B1)
pyrodoxal group (B6) - Answers - What are the vitamins bacteria use to grow?
bacteria that can grow from the nutrients supplied - Answers - what are prototrophs?
bacteria that wont grow on simple agar plates.
requires special nutrients/space - Answers - what are fastidious organisms?
lag phase
logarithmic phase
stationary phase
death - Answers - what are the four phases of bacterial growth?
essentially all pathogenic organisms
obtains energy from organic compounds - Answers - what are heterotrophic bacteria?
synthesizers of own glucose
less apt to be pathogenic - Answers - what are photosynthetic organisms?
no sunlight or organic compounds
use inorganic compounds for energy
less apt to be pathogenic - Answers - what are autotrophic organisms?
need of oxygen to grow and survive - Answers - what is aerobic growth?
oxygen acts as the final electron acceptor for metabolism - Answers - what is aerobic
respiration?
aerobic respiration
anaerobic respiration
fermentation
photosynthesis - Answers - how can bacteria generate energy?
provides ATP and metabolic intermediates - Answers - what happens in aerobic
respiration?
, glycolysis
krebs cycle
electron transport chain - Answers - what are the pathways of aerobic respiration?
1 glucose ---2 pyruvates
net gain of 2 ATP
NADH generated - Answers - what happens in the glycolytic pathway?
1 glucose ---2 pyruvates
pyruvate is decarboxylated to form CO2 and acetyl coenzyme A
8 NADH, 2 FADH2 converted into more ATP later on
net gain of 2 ATP - Answers - what happens in the krebs cycle?
generate ADP and ATP
each NADH = 3 ATP
each FADH2 = 2 ATP - Answers - what happens in the electron transport chain?
same 3 pathways are aerobic
oxygen is not the terminal electron acceptor, rather, an oxygen containing salt is
less ATP produced - Answers - what happens in anaerobic respiration?
an organic compound is used as a terminal electron acceptor
generates energy primarily through the glycolytic pathway - Answers - what happens in
fermentation?
lactic acid
ethanol
acetic acid
butyric acid - Answers - what are the end products of fermentation?
penicillins
cephalosporins
monobactams
carbepenems
glycopeptides - Answers - what are examples of cell wall active agents?
erythromycin
clindamycin
chloramphenicol
streptogramins
oxazolidinones - Answers - examples of 50 s-ribosome protein synthesis inhibitors?
aminoglycosides
tetracyclines
