Endospore: Structure Flashcards
1
Q
is the core metabolically active?
A
no it in INACTIVE
2
Q
how does less H2O than a vegetative cell help endopsores
A
resist to heat and chemicals
3
Q
what does accumulation of calcium dipicolinic acid complexes do
A
bind free H2O helping to dehydrate the core. this increases heat resistant of proteins and DNA, dehydration also inactivates enzymes
4
Q
what is the cortex
A
layer of loosely linked peptidoglycan in btwn the 2 membranes
5
Q
what are spore coats made from
A
layers of very tough proteins held together by lots of disulfide bonds
6
Q
what is the exosporium
A
thin layer of protein
