Describe the process of oxidative respiration.

O2 in converted into a O2 radical called superoxide by NADPH oxidase. These are harmful substances, then they are converted into peroxide (H2O2) by superoxide dimutase. Then these H2O2 can be converted by myeloperoxidase into HOCl to kill the bacteria invading the body. These are happening in phagolysosome of the neutrophils.
