Although rotenone is a respiratory enzyme inhibitor, and acting between NAD+ and coenzyme Q, resulting in failure of the respiratory functions [5], the relationship between structure and activity of rotenone and respiratory enzyme is still not clear.
These supramolecular structures provide kinetic advantage such as substrate channeling, increased efficiency in electron transport, prevention of destabilization, and degradation of respiratory enzyme complexes [21] and means to regulate ROS levels in the cell (most of the mitochondrial ROS originates from complexes I and III) [69] and hence, homeostasis.

Scientists from the University of California at San Diego report that fluoride switches off the enzyme cytochrome C oxidase, an oxygen carrying respiratory enzyme; deficiencies of this vital enzyme have been linked to cancer, severe diseases and even cot death (J Biol Chem, 1984; 259: 12984-88).
This disturbance would be partially explained by the interference of some heavy metals in respiratory enzyme activities and hence in the mechanism of phosphorylation of ADP to ATP by the ATPase.
