In cellular respiration, what goes in and what comes out? (in the presence of oxygen) -
CORRECT ANSWER-pyruvic acid goes in, acetyl- coA synthesizes, Krebs cycle begins and ATP,
FADH, NADH, CO2 come out.
Electron Transport chain results in what? - CORRECT ANSWER-ATP produced and results in 34
ATP
what are enzymes? - CORRECT ANSWER-they are organic catalysts that increase the likelihood
of a reaction, they also lower the activation energy and bind to a substrate (specifically an active
site)
What are the factors that affect enzymes? - CORRECT ANSWER-temperature, pH, presence of
inhibitors, competitive or non competitive (ALL ENZYMES ARE DIFFERENT AND HAVE DIFFERENT
REQUIREMENTS)
Photoautotrophs description - CORRECT ANSWER-use carbon dioxide as a carbon source and
light energy from the environment to make their own food.
,Chemoautotrophs description - CORRECT ANSWER-use carbon dioxide as a carbon source but
catabolize organic molecules for energy.
Photoheterotrophs description - CORRECT ANSWER-acquire energy from light and acquire
nutrients via catabolism of organic compounds.
Chemoheterotrophs desription - CORRECT ANSWER-use organic compounds for both energy
and carbon
oxygen is essential for (a.) and deadly for (b.) - CORRECT ANSWER-a. obligate aerobes
b. obligate anaerobes
______________ and ______________ can live with or without oxygen. - CORRECT ANSWER-
Facultative anaerobes and aerotolerant microbes
what is the description of Psychrophiles - CORRECT ANSWER-(below 15°C and can even
continue to grow at temperatures below 0°C, die at temperatures much above 20°C)=snowfield,
ice, cold water.
what are the 4 stages of a growth curve? - CORRECT ANSWER-1. lag phase
2. Expnential/ logrithmic growth phase
3. stationary phase
4.Death phase
lag phase - CORRECT ANSWER-"flat" period of nutrient/environment adjustment, enlargement;
little growth
, Exponential/Logrithmic growth phase - CORRECT ANSWER-a period of maximum growth will
continue as long as cells have adequate nutrients & a favorable environment. *Bacteria are
most susceptible to antimicrobial drugs.*
stationary phase - CORRECT ANSWER-rate of cell growth equals rate of cell death cause by
depleted nutrients & O2, excretion of organic acids & pollutants
death phase - CORRECT ANSWER-as limiting factors intensify, cells die exponentially in their
own wastes
cellular arrangement of stretococci - CORRECT ANSWER-coccus (round) arragned in chains
cellular arrangement of streptobacilli - CORRECT ANSWER-bacillus (rod) arranged in chains
cellular arrangement of staphylococci - CORRECT ANSWER-coccus (round) arranged in irregular,
grape-like clusters
cellular arrangement of staphylobacilli - CORRECT ANSWER-bacillus (rod) arranged in irregular,
grape-like clusters
endospores are produced by - CORRECT ANSWER-gram positive bacillus (anthrax) and
clostridium (tetnus)
what are the 3 most common forms of reproduction for prokaryotes - CORRECT ANSWER-binary
fission (most common), snapping division, and budding
what requires extreme conditions to survive? ( temp, pH, and or salinity) - CORRECT ANSWER-
extremeophiles
