ROSs form as a natural byproduct of the normal metabolism of Oxygen but can damage cell membranes by causing Oxidative Stress . Cells are normally able to defend themselves against ROS damage through the use of the Enzymes Superoxide Dismutase (SOD) and Catalase . The effects of ROS on cell metabolism have been well documented in a variety of species. These include not only roles in programmed cell death and Apoptosis , but also positive effects such as the induction of host defense Genes and mobilisation of ion transport systems. This is implicating them more frequently with roles in Oxidative Signalling . In particular, Platelets involved in Wound repair and Blood Homeostasis release ROS to recruit additional platelets to sites of Injury . These also provide a link to the adaptive Immune System via the recruitment of Leukocytes Reactive oxygen species are implicated in cellular activity to a variety of inflammatory responses including Cardiovascular Disease and Hearing Impairment via Cochlea r damage induced by Elevated Sound Levels .
