Introduction There are many ways cells dispose of toxic molecules in order to maintain the necessary internal environmental conditions to survive. These toxic molecules are known as free radicals that contain an unpaired electron on the outer orbit (Proljsak et al.2013). Some examples of free radicals that can be found in the cell are superoxide (O2-)‚ hydrogen peroxide (H2O2) and even reactive metals like copper and iron. These free radicals are produced based on the environment the individuals
