For penetration, viruses use

  • A.Specific receptors
  • B.Lysozyme
  • C.The mechanism called viropexia
  • D.The synthetic machinery of host cell

Answer: C

Correct answer: The mechanism called viropexia

Viropexis is the engulfment of the attached virus particle by the cell membrane, which folds round it and takes it in as a vesicle - receptor-mediated endocytosis. Enveloped viruses have a second option, fusing their envelope directly with the plasma membrane.
