• 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 Krebs cycle.
