  1. 3. a series of protein complexes and other molecules that transfer electrons from electron donors to electron acceptors
  2. 7. electron carrier involved in glycolysis
  3. 8. second stage of cellular respiration in which pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions
  4. 9. organic compounds required by many enzymes for catalytic activity
  5. 10. also known as the Krebs cycle, is a chain of reactions occurring in the mitochondria, through which almost all living cells produce energy in aerobic respiration
  6. 12. innermost compartment of the mitochondrion
  7. 15. process by which cells release energy in the absence of oxygen
