The oxidative environment and protein damage
WebbRespiratory burst (or oxidative burst) is the rapid release of the reactive oxygen species (ROS), superoxide anion (O − 2) and hydrogen peroxide (H 2 O 2), from different cell types.. This is usually utilised for mammalian immunological defence, but also plays a role in cell signalling.Respiratory burst is also implicated in the ovum of animals following …
