  4. CO2 is reduced to form sugars
  5. all of the above
College Biochemical Pathways
What happens during chemiosmosis?
  1. energy is released as H+ ions move feely across mitochondrial membranes
  2. H+ do NOT play any role in the production of ATP molecules
  3. a concentration gradient is generated when large numbers of H+ ions are passively transported from the matrix of the mitochondrion to the mitochondrion's intermembrane space
  4. ATP is synthesized when H+ ions move through a channel in ATP synthase
