Treatment with H 2 O 2 increased the Ca 2+ concentration in low temperature stress affected tobacco plant (Price et al
A second hydrogen peroxide molecule acts as a reducing agent to regenerate the resting state enzyme, producing a molecule of oxygen and water.36 Hydrogen peroxide though at low amounts tends to regulate some physiological processes such as signaling in cell proliferation, cell death, carbohydrate metabolism, mitochondrial function, and platelet activation and maintenance of normal thiol redox-balance,37 however, at high concentrations it has been reported to be very deleterious to cells.38 Hence, the ability of CAT to effectively limit H2O2 concentration in cells underlines its importance in the aforementioned physiological processes as well as being a first line antioxidant defense enzyme
Processed foods containing artificial additives, oxidized oils, and pro-inflammatory compounds further challenge the body's detoxification capacity
The deletion of the gpoA gene, as well as other associated genes including tpxD and ahpD , led to pronounced sensitivity to 2 0 mM H 2 O 2 , underscoring their involvement in ROS defense mechanisms
