Antigens And Phagocytosis Flashcards
1
Q
What are antigens?
A
• An antigen is a protein/glycoprotein
• that stimulates an immune response/the production of a specific antibody
2
Q
What are phagocytes?
A
white blood cells (including macrophages) that destroy pathogens by engulfing
them
3
Q
Phagocytosis model answer
A
• Phagocyte recognizes antigen
• Pathogen is engulfed into a phagosome
• Lysosome fuses with phagosome forming a phagolysosome
• Lysozyme enzymes hydrolyse pathogen
• Antigens from pathogen may be presented on the surface of the cell
