Rotenone is a poison commonly added to insecticides. Rotenone binds tightly with one of the electron carrier molecules in the el
ectron transport chain, preventing electrons from passing to the next carrier molecule. Insects exposed to rotenone will die because they will no longer be able to produce adequate amounts of ATP. T/F
Rotenone is a broad spectrum pesticide and insecticide and isalso considered as a non-selective piscicide.
The action mechanism of the rotenone has been described below -
It interferes with the electron transport chain which occurs in mitochondria of the cells. Here the transfer of electrons from complex I to the ubiquinone is inhibited by the rotenone. As a result, ATP formation with the help of NADH is also inhibited. When electron transport fails, oxygen in the cell is reduced to oxygen radical which further damages DNA and other components present in the mitochondria.
