BIO 250 EXAM 2 UPDATED ACTUAL Questions and CORRECT
Answers
grows everything (most non-fastidious bacteria) general purpose medium
know exactly what's in it defined medium
bunch off stuff in it but too complex to know complex medium
examples are blood and extract complex medium
grow one type but not the other selective media
there's a growth plate that just grows gut bacteria. this is selective media
an example of
grow many but look different differential media
example of selective and differential media MacConkey medium
what's the selective agents of MacConkey medium? bile salts and crystal violet
1 multiple choice option
incubutation phase, bacteria first inside you lag phase
bacteria growing at an exponential rate exponential phase
make their own carbon compounds starting with CO2 autotrophs
obtain carbon compounds from other organisms, humans heterotrophs
use inorganic chemical compounds lithotrophs
use organic chemical compounds organotrophs
bacteria, archaea, and some eukaryotic microbes that can extremophiles
grow in extreme environments
can grow at high temperatures thermophiles
examples are geysers and hot springs thermophiles
grow at high temperatures which occur under extreme hyperthermophiles
pressure
, example is the ocean floor hyperthermophiles
include the typical "lab rat" microbes, these are most mesophiles
pathogenic microorgganisms
grow at very low temperatures psychrophiles
microorganisms at locations deep in ocean that grow at barophiles
very high pressures
common near hydrothermal vents deep in the ocean barophiles
microorganisms that grow between pH 5-8, neutralophiles
microorganisms that grow best at pH 0-5
microorganisms that grow best at pH 9-11 alkaliphiles
require oxygen for energy metabolism obligate aerobes
survive only in environments with oxygen obligate aerobes
don't require oxygen for energy metabolism obligate anaerobes
survive only in environments without oxygen obligate anerobes
aerobic and anaerobic, survive with or without oxygen facultative anaerobes
a mass of bacteria that stick to and multiply on a solid biofilms
surface
contact lenses, bacteria on teeth, full catheters biofilms
examples are clostridium & bacillus endospores
what are live, active cells of endospores called? vegetative
most ATP is made in which phase? electron transport
carbs, lipids, and proteins are chemically broken down catabolism
1 multiple choice option
smaller biomolecules (amino acids, fatty acids, simple anabolism
sugars) are produced 1 multiple choice option
loss of electrons oxidation
