Electron Transport Chain and Chemiosmosis

What process(es) occur within the inner mitochondrial membrane/cristae?

• Kreb's Cycle

• Electron Transport Chain

• Chemiosmosis

• Both Electron Transport Chain AND Chemiosmosis

Which of the following happen during the Electron Transport Chain?

• High energy electrons travel down the ETC, pumping H⁺'s into the intermembrane space

• H⁺'s travel down the ETC, pumping high energy electrons into the intermembrane space

• H⁺'s diffuse through ATP Synthase, turning it so it can make ATP
