Overview Of Phagocytosis In Bacferial Cell Flashcards
1
Q
What happens when a neutrophil encounters a pathogen ?
A
Sends out cytoplasmic process to engulf pathogen
2
Q
What is the cytoplasmic process called ?
A
Lamellipodia
3
Q
When is cytoplasmic process efficient ?
A
When the pathogen is opsonised with a complement or antibody
4
Q
Why is this?
A
Because the neutrophil has surface receptors that bind to the complement and receptors which bind fo antibody
5
Q
What happens after injestiom?
A
Pathogen is enclosed with a phagosome inside a neutrophil
6
Q
What are the 2 mechanisms for killing the inhested pathogen ?
A
Respiratory hurts and digestion
7
Q
What does respiratory burst do?
A
Lead to the destruction of the pathogen by oxidative attack
8
Q
What does digestion do?
A
Uses lysosomal enzymes to degrade the cell wall peptidoglyxan of bacteria
