Verified step by step guidance

Begin by understanding the role of neutrophils in the immune system. Neutrophils are a type of white blood cell that play a crucial role in defending the body against infections.

Neutrophils use various mechanisms to kill bacteria, one of which involves the active metabolism of oxygen. This process is essential for producing reactive oxygen species.

The term 'respiratory burst' refers to the rapid release of reactive oxygen species, including bleach (hypochlorous acid) and hydrogen peroxide, by neutrophils. This burst is a key mechanism for destroying pathogens.

Differentiate between the terms provided: 'chemotaxis' is the movement of cells towards chemical stimuli, 'diapedesis' is the movement of cells through blood vessel walls, and 'amoeboid movement' refers to the crawling-like movement of cells. None of these terms describe the oxygen metabolism process.

Conclude that the correct term for the process of neutrophils metabolizing oxygen to produce bleach and hydrogen peroxide is 'respiratory burst'. This is a specific and critical function of neutrophils in the immune response.
