MICR 221 Exam Questions With Correct
Answers
geogemma barossi - CORRECT ANSWER✔✔-can grow at 121 C
| | | | | | | |
This bacteria is introduced to some substrates. Substrate A and B end up
| | | | | | | | | | | |
concentrated in the cell, while C and D do not. When osmotic shock
| | | | | | | | | | | | | |
happens, the intake of A is affected, but not B, C, or D. There is a
| | | | | | | | | | | | | | | |
permease for C. D is found only outside the cell, but inside the cell there
| | | | | | | | | | | | | |
is a phosphorylated version of D. How does each substrate get into the
| | | | | | | | | | | | | |
cell
|what is the energy source for each - CORRECT ANSWER✔✔-Substrate A
| | | | | | | | | |
|is protein dependent active transport, B is protein independent, C is
| | | | | | | | | | |
facilitated diffusion, and D is PTS | | | | |
A is ATP, B is proton gradient, C is no energy required, and D is high
| | | | | | | | | | | | | | | |
energy phosphate from PEP | | |
from a sewer sample, you find it contains sterols, n-acetyltalosimuronic
| | | | | | | | | |
acid, and KDO. - CORRECT ANSWER✔✔-it contains archaea, gram
| | | | | | | | |
negative, and mycoplasma | |
, what is true about s layers - CORRECT ANSWER✔✔-s layer prevents
| | | | | | | | | | |
something fetus from being macrophaged in humans| | | | | |
question with competence for both streptococcus and the H bacteria -
| | | | | | | | | | |
CORRECT ANSWER✔✔-the H bacteria gives streptococcus dna for toxins
| | | | | | | |
thru transformation. not plasmid conjugation
| | | | |
question just about streptococcus and how it becomes competent -
| | | | | | | | | |
CORRECT ANSWER✔✔-competence factor is released, single stranded
| | | | | | |
dna enters, and autolysin reveals stuff
| | | | |
a picture of bacteria with flagella asking what type - CORRECT
| | | | | | | | | | |
ANSWER✔✔-i. peritrichous ii. monotrichous | | |
Che-Y-P - CORRECT ANSWER✔✔-increases when the cell swims towards
| | | | | | | | |
an increasing gradient of repellent
| | | |
What is true about spores? - CORRECT ANSWER✔✔-resistant to
| | | | | | | | |
dessication, heat, chemical agents, irradiation | | | |
If a bacteria can't make PapC what happens - CORRECT ANSWER✔✔-no
| | | | | | | | | | |
pili
