Phagocytosis

Question 1

What is the process of phagocytosis

Answer 1

Phagocyte detects chemicals released by pathogen and moves towards it
Phagocyte binds to antigen on phagocyte cell membrane
Phagocyte engulfs pathogen via endocytosis forming a phagosome inside phagocyte
Phagosome fuses with lysosome inside phagocyte to form phagolysosome
Lysozymes inside phagolysosome hydrolyse pathogen into small molecules
Smaller soluble useful molecules absorbed into cytoplasm
Waste molecules removed via exocytosis
