Question

Phospholipid molecules of cell membrane possess

• A. One polar head and one polar tail
• B. One non polar head and one non-polar tail
• C. One non polar head and two non-polar tail
• D. One non polar head and two polar tails

Answer 1

The correct option is C One non polar head and two non-polar tail

• The cell membrane is a phospholipid bilayer that are selectively permeable membranes which separate the interior of the cells (cell organelles and cytoplasm) from the outside environment or the extracellular space.
  
• These biological membranes are composed of lipid bilayers that form a continuous layer.
• It is made up of amphiphilic phospholipids which have both hydrophilic phosphate head and a hydrophobic tail that consists of two fatty acid chains.
• They have a polar head group and two non-polar hydrocarbon tails.
• So, the correct answer is 'One polar head and two non-polar tails'.
