Macrophages and neutrophils express several enzymes that are involved in biochemical mechanisms that kill ingested microbes. Which of the following is NOT an enzyme expressed by these cells?
A. Inducible nitric oxide synthase (iNOS)
B. Granzyme B
C. Phagocyte oxidase
D. Myeloperoxidase
E. Lysozyme

Granzyme B is a type of serine protease that is present in granules cells such as cytotoxic T cells and natural killer cells. This enzyme plays an important role in the process of mediate apoptosis.

Neutrophils are a type of white blood cell that plays an important role in immunity. These cells produce many enzymes such as Myeloperoxidase, Lysozyme, Hydrolases and some other.
