What reactive species is primarily generated by myeloperoxidase in neutrophils?

Explanation:
Hypochlorous acid is the reactive species produced by myeloperoxidase in neutrophils. During the respiratory burst, neutrophils generate hydrogen peroxide using NADPH oxidase. Myeloperoxidase then uses this hydrogen peroxide and chloride ions to form HOCl, a powerful antimicrobial oxidant that kills microbes by oxidizing proteins, lipids, and nucleic acids. Hydrogen peroxide and superoxide are upstream reactive oxygen species that feed into this pathway, while nitric oxide is produced by other cellular pathways and is not generated by myeloperoxidase.
