Practice questions

1 of 20Practice questions for this set
In an experiment, isolated mitochondria are supplied with NADH and ADP + Pi. When oxygen is removed from the chamber, electrons can no longer be transferred to the final electron acceptor in the electron transport chain. As a result, proton pumping across the inner mitochondrial membrane decreases, reducing the proton-motive force that drives ATP synthase. The citric acid cycle enzymes remain present, but their ability to regenerate NAD+ depends on electron flow through the chain. No inhibitors of ATP synthase are added. Which outcome is most likely when oxygen is absent?
