Mitochondrial complex I is a large protein complex located in the inner mitochondrial membrane. During cellular respiration, this complex uses energy to transport hydrogen ions (H+) against their concentration gradient. The steps of (H+) transport carried out by mitochondrial complex I are depicted in the following diagram: Given the concentration gradient established by mitochondrial complex I, which of the following movements can occur?
