5.2- Phagocytosis 0.0 / 5 ? BiologyCell recognition and the immune systemASAQA Created by: Megan2413Created on: 15-01-17 13:01 What is phagocytosis? A process by which pathogens are engulfed by a type of white blood cell called a phagocyte 1 of 10 What type of immune response is phagocytosis? Non-specific immune response 2 of 10 How is the phagocyte attracted to the pathogen? The phagocyte is attracted to the chemical products released by the pathogen 3 of 10 How does the pathogen approach the phagocyte? Along a concentration gradient created by the chemical products it releases 4 of 10 How do the phagocyte and pathogen attach to each other? The phagocyte contains several receptors on its cell-surface membrane that bind to chemicals on the surface of the pathogen 5 of 10 Once the phagocyte is engulfing the pathogen, what organelle surrounds it? Lysosmes 6 of 10 What has the phagocyte now formed? A phagosome vesicle 7 of 10 What is released into the phagosome once the pathogen has been engulfed? Lysozymes 8 of 10 What do the lysozymes do to the pathogen? They destroy ingested bacteria by the hydrolysis of its cell wall 9 of 10 What happens to the soluble products from the breakdown of the pathogen? They are absorbed into the cytoplasm of the phagocyte 10 of 10
