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 the NAD⁺ and FAD that are accepted by electrons in glycolysis and the Krebs cycle.

Question

Quizplus · Accepted Answer

The translocation of protons creates an electrochemical gradient across the inner mitochondrial membrane. This gradient serves as the driving force for ATP synthesis by oxidative phosphorylation. The energy released from the movement of protons down the gradient is used to add phosphate groups to ADP, forming ATP.
