Across
  1. 3. energy needed to start a reaction
  2. 4. bind to an area other than the active site (allosteric site), which changes the shape of the active site preventing substrates from binding
  3. 7. a change in the physical structure of the enzyme (Activesite)
  4. 10. macromolecules that catalyze (speed up) reactions by lowering the activation energy
  5. 14. molecules bind (noncovalent interactions) to an allosteric site which changes the shape and function of the active site
  6. 17. the released phosphate in ATP moves to another molecule to give energy
  7. 18. reactions that absorb energy
  8. 19. reduce enzyme activity by blocking substrates from binding to the active site
  9. 21. nonprotein molecules that assist enzyme function and increases its efficiency
  10. 22. reactions that release energy
