Phagocytosis Quiz

Neutrophils and macrophages engulf and destroy microbes through this process.

These receptors on phagocytes are key for recognizing and binding to microbes.

Phagocyte oxidase converts oxygen into superoxide and free radicals.

This enzyme converts arginine to nitric oxide in macrophages, aiding in microbial killing.

An inherited condition caused by a deficiency in the phagocyte oxidase enzyme.

Extracellular traps used to trap and kill bacteria and fungi.

Enzymes and ROS released during inflammation can damage surrounding tissues.

This is the optimal size range for particles to be ingested through phagocytosis.

These two receptors can bind to microbes during phagocytosis, marking them for ingestion.

Molecular oxygen converts into superoxide anion and free radicals via this process.

Enzymes that break down microbial proteins within phagocytes.

Neutrophils respond to pathogens and inflammatory mediators by dying and releasing their nuclear contents.

Inherited deficiency impairs phagocyte oxidase enzyme leading to ineffective microbial killing.

These substances released to kill microbes can also harm host tissues.
