Rotenone Is a Poison Commonly Added to Insecticides

Rotenone is a poison commonly added to insecticides. Rotenone binds tightly with one of the electron carrier molecules in the electron transport chain, preventing electrons from passing to the next carrier molecule. Insects exposed to rotenone will die because

A) they will no longer be able to perform anaerobic respiration.
B) high levels of fermentation products will build up in their bodies.
C) they will no longer be able to produce adequate amounts of ATP.
D) they will no longer be able to absorb water and will become dehydrated.
