Human activites have greatly increased carbon dioxide levels in the atmosphere and nitrogen levels in the biosphere. Altered Altered biogeochemical cycle combined with climate change increase the vulnerability of biodiversity, food security, human health, and water quality to a changing climate.
Diaphorase or dihydrolipoyl dehydrogenase is a flavoprotein enzyme capable of oxidizing the reduced form of NAD (NADH). This lipoamide dehydrogenase is a component of the glycine cleavage system, as well as of the alpha-ketoacid dehydrogenase complexes. It binds one FAD per protein subunit. The enzyme is provided in 3.2 M ammonium sulphate.
Ozone would be the secondary pollutant because it is caused when two primary pollutants react. Hope this helps!
