Both superoxide production and the GDP-sensitive proton conductance were suppressed by rotenone plus an antioxidant.

Kinetic analysis of the proton leak showed that diabetic heart and muscle mitochondria were actually more coupled compared with control despite an approximate 2- to 4-fold increase in uncoupling protein-3 content.

Mitochondrial uncoupling protein 3 (UCP (3))-mediated uncoupling has been postulated to depend on several factors, including superoxides, free fatty acids (FFAs), and fatty acid hydroperoxides and/or their derivatives.
In the absence of FFAs, no differences in proton-leak kinetic were detected between succinate-energized mitochondria respiring in the absence or presence of rotenone, despite a large difference in complex I superoxide production.
