Q1
A researcher measures the effect of an uncoupler (a protonophore) on intact mitochondria oxidizing NADH-linked substrates. After adding the uncoupler, oxygen consumption increases while ATP production decreases. The inner membrane remains intact, and electron transport chain complexes are functional. Assume electron transfer to O$_2$ remains exergonic.
Which prediction would be expected given the redox reaction?
