Microbial life at high temperatures

Question 1

high t, change in protein sequence?

Answer 1

so the enzymes are not denatured by the high

temperature and can stay active.(enzymes are heat-stable)

Question 2

thermophilics?

Answer 2

Transport across the membrane functions optimally at high temperature.

Question 3

their cytoplasmic membrane requires?

Answer 3

Requires modification of the cytoplasmic membrane so it remains stable at
high temperatures

Question 4

for example,cytoplasmic modification?

Answer 4

lipid monolayer of Archaea

Question 5

need proteins that are

Answer 5

Heat‐shock proteins which help keep proteins in the active conformation.

Question 6

and protection mechanism

Answer 6

to ensure stability of DNA (GC rich).

Question 7

plus de CG?

Answer 7

pcq plus de hydrogen bond resistant

Question 8

Heat‐stable enzymes can be useful for

Answer 8

biotechnology (taq polymerase)

Question 9

Endospores help resist high temperatures but

Answer 9

they are not metabolically active).

Question 10

tag polymerase?

Answer 10

a technique for amplifying DNA and a major tool of modern biology
