Internal and External to the Cell Wall (part 3) Flashcards
What is the function of activation?
prepares the spore for germination
What kickstarts activation?
germination receptors within the inner spore membrane look for and recognize a specific AA in the environment
What happens once germination receptors are triggered during activation?
germination receptors will signal the degradation of dipicolinic acid and calcium for rehydration of the cell.
What does increased temperature do during activation?
allows for the activation of germination receptors and increased fluidity
What happens during germination?
the spore swells rupturing the spore coat, causing the release of spore components and loss of resistance
what is the function of the cortex lytic enzyme?
first new structure, degrades the cortex.
T/F the Cortex lytic enzyme will recognize any cortex
false, only the spore cortex
why does the CLE only recognize the spore cortex?
in order to protect the cell wall, only recognizes and breaks down the loosely linked peptidoglycan
The breakdown of the spore cortex allows for the ________ hydration of the core
complete
what happens during outgrowth?
New cell components are made, and emerge from the remains of the spore
what are SASPS? What is their function, where are they expressed?
small acid soluble proteins, expressed in the core, alter the PH of the core 9typically one unit lower)
What is the main role of SASPS?
bind to B DNA and allow DNA to adopt the A form (allowinf DNA to be better protected)
During the __________ stage of germination we see the cell begin a normal rate of metabolism
outgrowth
During the outgrowth stage, _________ are used to kickstart cells metabolism
SASPS
After outgrowth, the cells undergo _______ ________
binary fission
