Which of the following is directly used in oxidative killing of target cells?

Question

Quizplus · Accepted Answer

Hydrogen peroxide is directly used in oxidative killing of target cells. It is produced by phagocytes during the respiratory burst, which generates reactive oxygen species (ROS) that contribute to the destruction of bacteria and other invading pathogens. Lysozyme, defensin, and TNF-alpha are also involved in immune defense, but they do not directly participate in oxidative killing. Lysozyme hydrolyzes bacterial cell walls, defensins create pores in microbial membranes, and TNF-alpha mediates inflammation and apoptosis of infected cells.
