  3. 10. powerhouse of the cell where the majority of ATP is made
  4. 12. step of cellular respiration with the largest energy payoff producing up to 34 ATP molecules
  5. 14. molecule that acts like a "rechargeable battery" storing energy to be used in cells
  6. 15. The second law of thermodynamics says every conversion of energy is inefficient and results in some energy being lost as _________.
  7. 16. glucose is broken down to 2 pyruvate molecules with net gain of 2 ATP and 2 NADH
