  1. 2. ENERGY:The energy required to start any reaction
  2. 7. chemical reaction that absorbs free energy from the surroundings,
  3. 8. synthesis of complex molecules from simpler ones, which requires an input of energy
  4. 10. in the active site, the chemical reaction can take place.
  5. 11. chemical reaction that releases free energy to the surroundings
  6. 13. substance that is formed as a result of a chemical reaction
  7. 14. KEY: The substrate molecules fit perfectly into active site, like a key in a lock.
