Effects Of Media

Biological systems activate ground-state dioxygen (3O2) for controlled energy transduction and chemical syntheses via electron-transfer and hydrogen-atomtransfer reduction to O2-, HOO·, and HOOH. These reduction products are further activated with metalloproteins to accomplish oxygen atom-transfer chemistry. Conversely, green plants via photosystem II facilitate the oxidation of chemistry.
