In most animals, the metabolic reactions and hence all the physiological functions proceed optimally in a narrow temperature range (in humans, it is – 370c). but there are microbes (archaebacteria) that flourish in hot springs and deep sea hydrothermal vents where temperatures far exceed 1000c. how is this possible?
Answers
Let's talk about Archaebacteria,
They occur in harsh habitats such as marshy area, extreme salty areas, hot springs, high temperature , high acidic or alkaline ph
actually, their plasma membrane posess branched chain lipids, this feature is responsible for their survival in extreme conditions.....
they have q diff.cell wall from other prokaryotes, but note that that feature is not responsible for their survival

Answer:
Archaebacteria Cell Membranes – there are different kinds of bonds in the phospholipids molecules that link the lipids (tails) to the glycerol molecule (head); these bonds are stronger and may help these bacteria survive extreme temperature and pH. They have thermostable proteins as enzymes in their cells to complete metabolic reactions.
Explanation:
Archaebacteria (Thermophiles) are ancient forms of bacteria found in hot water springs and deep sea hydrothermal vents. They are able to survive in high temperatures (which far exceed 100°C) because their bodies have adapted to such environmental conditions. These organisms contain specialized thermo-resistant enzymes, which carry out metabolic functions that do not get destroyed at such high temperatures.
