5.2- Phagocytosis Flashcards
1
Q
What do phagocytes do?
A
They ingest and destroy the pathogen before it can do any harm.
2
Q
How are the phagocytes attracted to the non-self material?
A
The phagocytes have several receptors on their cell-surface that helps to recognise foreign material.
3
Q
What is the second step in phagocytosis? (After the Phagocyte has moved towards the non-self material)
A
The phagocyte will engulf the foreign material to form a vesicle known as a phagosome.
4
Q
What does the lysosome do once the foreign material has been engulfed?
A
Release lysozymes which are enzymes that help to destroy ingested bacteria by hydrolysis.
5
Q
What happens once the bacteria has been broken down by hydrolysis?
A
The hydrolysis products are absorbed by the phagocyte.
