All of the following enzymes may contribute in generating free oxygen radicals within neutrophils for killing intracellular bacteria, except-
Superoxide dismutase
Fenton's reaction
NADPH oxidase
Glutathione peroxidase
NADPH oxidase called the phagocyte oxidase, which oxidizes NADPH (reduced nicotinamide adenine dinucleotide phosphate) and, in the process, conves oxygen to superoxide ion (O2 * ) Superoxide is then conveed by superoxide dismutase into hydrogen peroxide (O2 * + 2H+ - H2O2) glutathione peroxidase major function is to protect cells from oxidative damage by regeneration of glutathione. Fenton reaction: H2O2 + Fe2+ -Fe2++ OH- + OH. ref robbins basic pathology 9th ed page 38
