Final answer:
The assembly of NADPH oxidase on the phagolysosome generates superoxide radicals.
Step-by-step explanation:
The assembly of NADPH oxidase on the phagolysosome generates superoxide radicals. NADPH oxidase is an enzyme complex involved in the immune response, specifically in the process of oxidative burst. During oxidative burst, NADPH oxidase catalyzes the conversion of oxygen molecules into superoxide radicals, which help in the killing of bacteria and other pathogens.
