Microcapsules are composed of

  • A.proteins
  • B.polysaccharides
  • C.lipids
  • D.all of these

Answer: D

Correct answer: all of these

A capsule or microcapsule may be built of polysaccharide, of polypeptide (as in Bacillus anthracis), or of glycoprotein and lipid material. Whatever its composition, it resists phagocytosis and helps the cell adhere - which is why capsulated strains are so often the virulent ones.
