1 markElectron transport chain inhibitors are molecules that disrupt the electron transport chain in cells. Some electron transport chain inhibitors function as uncouplers, breaking the connection between the electron transport chain and ATP synthase. Which of the following is the most likely effect of an uncoupler on oxidative phosphorylation?
Oxygen will still be used up but less ATP will be produced.
Oxygen use and ATP production will both decrease.
Fewer protons will be pumped across the inner mitochondrial membrane.
Less heat is generated.
