Why do the cell membranes of microbes living in Arctic water likely contain more unsaturated fatty acids than do membranes of microbes living in hot springs?


Expert Answer

Step 1
  • The plasma membrane is an important interface between the extracellular and intracellular environments. It allows the exchanges of molecules, gases, mediates cellular processes like endocytosis and signaling.
  • The fluidity of the plasma membrane is essential for these processes to take place. The membrane is composed of a phospholipid bilayer with the polar head groups exposed on the extracellular and intracellular space. The fatty acid chain is buried in the middle of the bilayer.
  • The unsaturated fatty acids are responsible for the fl...
