Hi I'm Cynthia Bueche and I'm here with esteemed Harvard Professor, Nick Bastanfar.
And today he is going to tell us about how our chemical atrazine inhibits photosystem 2.
The chemical atrazine inhibits photosystem 2 and ATP formation by blocking electron transportation.
Atrazine reduces the extraction of electrons from water by clusters of Manganese.
The electrons are then dropped onto chlorophyll molecules.
And as the electrons continue to accumulate on the chlorophyll molecules, they cause rates of oxidation that
the weeds cannot tolerate. Therefore the plant dies.
