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

Question

Quizplus · Accepted Answer

The translocation of protons to the outer mitochondrial compartment creates an electrochemical gradient, with a higher concentration of protons in the outer compartment than in the inner compartment. This gradient can then be used by ATP synthase to generate ATP from ADP and inorganic phosphate, in a process called oxidative phosphorylation. Therefore, translocating protons helps the mitochondria produce energy by creating the electrochemical gradient necessary for ATP synthesis.
