The Energy of Electron Transport Serves to Move (Translocate) Protons

question 30

Multiple Choice

The energy of electron transport serves to move (translocate) protons to the outer mitochondrial compartment. How does this help the mitochondrion produce ATP?

• A) The hydrogen ions (protons) are transferred to oxygen in an energy-releasing reaction.
• B) The translocation of protons sets up the electrochemical gradient that drives ATP synthesis in the mitochondria.
• C) The protons pick up electrons from the electron transport chain on their way through the inner mitochondrial membrane.
• D) The protons receive electrons from the NAD+ and FAD that are accepted by electrons in glycolysis and the citric acid cycle.
