illness. Walter Cannon used it in 1926 to refer to external factors that disrupted what he called homeostasis. Homeostasis is a concept central to the idea of stress. In biology‚ most biochemical processes strive to maintain equilibrium‚ a steady state that exists more as an ideal and less as an achievable condition. Environmental factors‚ internal or external stimuli‚ continually disrupt homeostasis; an organism’s present condition is a state in constant flux wavering about a homeostatic point

The cell uses antioxidants‚ like MnSOD‚ to slow down or prevent substrate oxidation. For example‚ converting superoxide to hydrogen peroxide. The free radical conversion allows moderate ROS formations that are beneficial to the cell when redox homeostasis is maintained. The main purpose of ROS production is not only the end product of a reaction but it is used by the cell as signaling molecules to run other metabolic pathways‚ like cell proliferation glucose metabolism cellular growth and many other
