Phagocytosis

Cards (3)

  • Describe the process of phagocytosis
    • chemical products of pathogens act as attractants
    • phagocytes move down concentration gradient
    • phagocyte's receptors attach to chemicals on surface of pathogen
    • pathogen engulfed, forming a phagosome
    • lysosomes fuse with phagosome
    • lysosomes release lysozymes that destroy bacteria
    • soluble products from breakdown absorbed into cytoplasm
  • What is a vesicle?
    a small fluid-filled sac or cavity in the body
  • What is cytokinesis?
    small proteins that are important in cell signalling
