Peroxidases, one of the key antioxidant enzymes, are widely distributed in nature and
catalyze oxidation of various electron donor substrates concomitant with the decomposition …

The two forms of inorganic arsenic, arsenate (AsV) and arsenite (AsIII), are easily taken up
by the cells of the plant root. Once in the cell, AsV can be readily converted to AsIII, the more …
