Phagocytosis

• Define phagocytosis


  The process where phagocytes engulf and destroy material
• step 1 of phagocytosis ?

  • Cell ingests/engulfs the antibody
  • Cell membrane surrounds the antibody (to take it inside the cell)
• Step 2 of phagocytosis?

  Lysosomes fuse with vesicle/phagosome
• Step 3 of phagocytosis

  Lysozymes breakdown/digest the antibody
• phagocytosis stage 1 ?

  phagocyte engulfs pathogen (endocytosis)
• Phagocytosis stage 2


  Forming vesicle/phagosome and fuses with lysosome;
• phagocytosis stage 3


  Enzymes digest/hydrolyse

  ( Accept lysozymes for ‘enzymes’ )
