Question

To limit the damage by respiratory burst, what happens?

A) Formation of neutrophil extracellular traps (NETs)
B) Activation of antioxidant enzymes
C) Release of anti-inflammatory cytokines
D) Apoptosis of neutrophils

Answer 1

To limit damage during a respiratory burst, the body uses antioxidant enzymes to neutralize harmful reactive oxygen species, and if necessary, induces apoptosis of neutrophils to remove damaged cells.

Step-by-step explanation:

To limit the damage caused by a respiratory burst, the body activates antioxidant enzymes. These enzymes help to neutralize harmful reactive oxygen species produced during the vigorous respiratory burst that neutrophils perform to kill pathogens. During a respiratory burst, neutrophils generate large amounts of reactive oxygen species which can cause collateral damage to surrounding tissues. The role of antioxidant enzymes such as superoxide dismutase, catalase, and various peroxidases is to break down these reactive molecules, thus protecting the tissues from oxidative stress. Additionally, in cases where damage is extensive, apoptosis of neutrophils may also occur, clearing up the dead cells and limiting further harm to the tissue.
