Growth

Question 1

förklara vad FtsZ ringen gör i celldelningen

Answer 1

Hjälper att dela på cellen. Drar ihop sig (contracts)
i mitten så att den tillslut blir till två delar.
Provides force that divides the cell.

Question 2

vilken typ av delning använder bakterier sig av?

Answer 2

binary fission

Question 3

describe the cell wall formation

Answer 3

Autolysin breaks bonds in preexisting peptidoglycan
while transglycosylase synthesises them

Transpeptidation reaction that leads to cross-linking

Question 4

describe the Min CDE system

Answer 4

MinC —> highest concentration
MinC inhibits the formation of the FtsZ ring —> least concentration in the middle —> where the ring forms

Min E removes Min C

Question 5

which are the four types of control of microbial growth

Answer 5

antisepsis
sanitisation
disinfection
sterilisation

Question 6

describe the types of cell division that exists

Answer 6

1. equal cell division (binary fission)
2. unequal cell division

-simple budding off
-budding from hyphae
-cell division from stalked organism
-polar growth without differentiation of cell size
