Microbiology Exam #2

organism requirements, growth control, cellular respiration, diseases

organisms that gain energy from the sun phototrophs
organisms that result from the replication of a single cell pure culture
method with high heat, short time for treating foods high heat Pasteurization
control method that damages DNA and produces thymine dimmers UV Radiation
treatment effective against Pseudomonas spp., common bacteria of nosocomial infections Radiation
metabolic process that takes in carbon dioxide photosynthesis
metabolic process that produces NADPH pentose phosphate pathway
4 diseases that can be spread sexually AIDS, Syphilis, Gonorrhea, Chancroid
process that produces ATP by adding phospahate directly to ADP substrate level phosphorylation
optimal temperature for mesophiles 20*C-45*C
reduction of microbes to reach health standards sanitation
destroys microbes, including endospores, But can be mutagenic ethylene oxide
reduced when glucose is oxidized NAD & FAD
end products of glycolysis 2 each of ATP, NADH, Pyruvate
at the end of this process the energy acceptor is pyruvate, an organic compound fermentation
organism that needs oxygen for metabolism obligate aerobe
organism that uses preformed organic molecules as carbon source and energy source chemoheterotroph
type of causitive agent of Dengue virus
causitive agent is Borrelia burdorferi Lyme disease
disease caused by trematode that normally affects birds Swimmers itch
disease caused by Gonyaulax spp. Paralytic Shellfish Poisoning
disease treated with an antifungal Sporotrichosis
technique that adds chemicals (generally salt or sugar) to increase shelf life of foods preservation
organism that prefers oxygen but does NOT need it facultative anaerobe
organism that gains carbon from organic molecules and gets energy from the sun chemoautotroph
organism that uses carbon dioxide as a carbon source autotroph
medium that enhances the growth of one particular organism in a mixed population selective media
type of control that, unlike a disinfectant, is nontoxic enough to be used on human skin antiseptic
time it takes to kill 90% of a population D time
control method that kills bacteria by damaging DNA UV light
# of ATP generated by glycolysis 2-4
causitive agent of filariasis Wuchereria bancrofti (roundworm)
type of subunit that uses beta oxidation fatty acid
enzyme that breaks up starch amylase
2 problems with overuse of antimicrobials resistance & toxicity
outputs of transition step 2 each of Acetyl CoA, NADH, CO2
outputs of TCA/Krebs Cycle 6 NADH, 2 FADH2, 2 ATP, 4 CO2
outputs of electron transport chain 10 NAD, 2 FAD, 6 H2O, 30 ATP
maximum yeild of oxidative phophorylation 34 ATP
maximum yeild of substrate phosphorylation 4 ATP
