Question
Steps in phagocytosis in which the object is broken down and dissolved by digestive enzymes and other mechanisms?
Solution
Phagocytosis is a process where a cell engulfs a solid particle to form an internal compartment known as a phagosome. Here are the steps involved in phagocytosis where the object is broken down and dissolved by digestive enzymes and other mechanisms:
-
Recognition and Attachment: The first step in phagocytosis is the recognition and attachment of the particle to be engulfed by the cell. This is usually a foreign substance like a bacterium or a dead cell. The cell recognizes the particle through receptors on its surface.
-
Ingestion: Once the particle is recognized, the cell membrane surrounds it and engulfs it. This process is called ingestion. The cell membrane folds inwards and forms a pocket that encloses the particle. This pocket then pinches off to form a separate compartment within the cell, known as a phagosome.
-
Fusion with Lysosome: The phagosome then fuses with a lysosome, which is an organelle within the cell that contains digestive enzymes. The fusion of the phagosome and the lysosome forms a structure called a phagolysosome.
-
Digestion: Within the phagolysosome, the particle is broken down by the digestive enzymes. These enzymes break down the particle into its basic components, such as amino acids, sugars, and other small molecules.
-
Exocytosis: Once the particle has been completely broken down, the waste products are expelled from
