Across
  1. 6. effect of a product that decreases its further production by inhibiting the activity of the first enzyme in the pathway that produces it (two words)
  2. 8. inhibition in which the inhibitor competes with the substrate molecule by binding to the active site of an enzyme (two words)
  3. 11. study of energy flowing through living systems
  4. 14. energy transferred from one system to another that is not work
  5. 16. adenosine triphosphate
  6. 17. dynamic fit between the enzyme and its substrate where both components modify their structure to bind (two words)
