How is the hydrogen ion gradient created by the electron transport chain? High energy electrons move through protein complexes until they reach ATP synthase, which then uses that energy to pump hydrogen ions from the matrix to the intermembrane space High energy electrons move through protein complexes, which pump hydrogen ions from the matrix to the intermembrane space High energy electrons move through protein complexes, which open up protein complexes and allow hydrogen ions to diffuse from the matrix to the intermembrane space High energy electrons move through protein complexes until they reach ATP synthase, which then uses that energy to diffuse H+ ions from the intermembrane space to the matrix

NAD+ and FAD molecules are reduced in the Kreb's cycle to make high energy electron carriers. Where do these molecules come from before they are used in the Kreb's cycle? NAD+ is produced at ATP synthase and FAD is produced at the electron transport chain NAD+ is produced in pyruvate oxidation and FAD is produced at the electron transport chain NAD+ is produced during glycolysis, and FAD is produced at the electron transport chain Both NAD+ and FAD are produced at the electron transport chain 2 of
