The process of phagocytosis involve all of the following except
evablogger [386]

Hello, I figured your question was missing its options so I went online to find them. Here they are:

The process of phagocytosis involves all of the following EXCEPT :

a. adhesion.

b. secretion of cytotoxins.

c. elimination.

d. vesicle fusion.

e. chemotaxis.

Answer:

The correct answer is: b) secretion of cytotoxins.

Explanation:

Phagocytosis is a mechanism performed by cells in which the plasma membrane engulfs a large particle. Phagocytosis is used by cells in the immune system to ingest pathogens like viruses and bacteria.

Phagocytosis consists of many steps:

  1. activation - the phagocytes that were resting are activated in the inflammatory response when a pathogen enters the body.
  2. chemotaxis  - this refers to the process in which the phagocyte moves to the pathogen by following the chemical factors released by these germs.
  3. adhesion - the phagocyte attaches to the pathogen.
  4. ingestion /vesicle fusion - the phagocyte sends pseudopods to engulf the pathogen, and places it in a phagosome, which is an endocytic vesicle. The phagosome and the phagocyte will fuse so the pathogen gets inside.
  5. elimination - the pathogen is destroyed in the phagocyte by the lysosomes present in it.

<u>The</u><u> secretion of cytotoxins</u><u> is not a part of the phagocytosis, and is a process exclusive to </u><u>T cells</u><u> (leukocytes that lack the ability to phagocyte).</u>
