Across
  1. 2. Lower the ceiling and I have changed
  2. 6. After kinases act I silence receptors
  3. 9. Shift the curve sideways and I have changed
  4. 10. Released and received by the same cell asking whether to attack or restrain
  5. 15. Free water and pretzels if spelled incorrectly also how bases recognize partners
  6. 17. Active even without ligand modern theory requires me
  7. 19. Excluded from the final message maybe cutting losses is best
  8. 22. Kinases depend on me to spread signals
  9. 24. Lower dissociation constants mean more of me
  10. 25. Inhibited to slow certain breast cancers known in another language as cytochrome enzyme
Down
  1. 1. Even full receptor occupancy cannot lift the response to the top
  2. 3. Too much stimulation and receptors stop listening
  3. 4. Without me signals last longer than intended
  4. 5. Radical signals depend on me instead of vesicles
  5. 7. Maximal effect without full occupancy depends on me
  6. 8. Vesicles depend on me to release transmitters
  7. 11. Calcium binds me before contraction begins
  8. 12. Without me steroids cannot change physiology
  9. 13. Fits somewhere else attachment could be stronger though
  10. 14. A few receptors active yet response grows large
  11. 16. Bind and activate receptors defining pharmacological action
  12. 18. Bind without activation preventing response
  13. 20. Heavenly messenger that travels backward to quiet excitement
  14. 21. Without this sweet modification receptors may never arrive
  15. 23. Direction endocannabinoids prefer to travel
