The energy of electron transport serves to move (translocate)protons to the outer mitochondrial compartment.How does this help the mitochondrion to produce energy?
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 NAD⁺ and FAD that are accepted in glycolysis and the Krebs cycle.

Question

The movement of protons to the outer mitochondrial compartment creates an electrochemical gradient across the inner mitochondrial membrane. This gradient serves as the energy source for ATP synthesis by ATP synthase. Therefore, translocating protons helps the mitochondrion to produce energy by driving ATP synthesis.
