Question

Chemotaxis is the process of
   
  A. ingesting an invading bacteria.
  B. releasing destroyed bacteria from a phagocyte.
  C. attracting phagocytes to a site of injury.
  D. attaching a phagocyte to a bacteria cell wall.

Answer 1

The process of attracting the phagocytes to the site of injury is known as chemotaxis. The chemotaxis is a part of the inflammatory response of the body. The phagocytes once attracted to the site of the injury ingests the bacteria by attaching to the bacterial cell wall. The ingestion of the invading bacteria is known as phagocytosis. The destroyed bacteria is then released from the phagocytes.

Answer 2

Answer:

The correct answer is option C which is attracting phagocytes to a site of injury.

Explanation:

• Chemotaxis is the movement of some organism in response to some chemical stimulus.
• Organism can move away or towards the stimulus.
• In our body, there are many immune cells( lymphocytes) circulating in blood.
• If there is injury on the skin, Injured skin cells and some immune cells present near to injury will release some chemicals known as cytokines, which attract the phagocyte towards the injury site to engulf microbes.
•
