  1. 5. Cyclase (AC) At the membrane's edge I stand, transforming ATP's embrace into a cyclic messenger the cell understands
  2. 6. I am a tireless catalyst, a master of speed, facilitating reactions with unrelenting fire to meet the cell's every need
  3. 7. Born from the original message, I echo its call, amplifying its impact throughout the cellular hall
  4. 9. Three parts entwined in a delicate dance, our fate is unsealed when GTP binds, and we respond to dissociation's call
  5. 11. I mimic the key, unlocking cellular responses, but tread carefully, for my touch can ignite both beneficial and dangerous fires
  6. 12. A loyal companion in this tripartite bond, I modulate the signal with alpha and gamma, our influence real, though often unseen
  7. 15. A molecular switch, I activate or silence with a phosphate's embrace, attached by kinases, removed by phosphatases, in a delicate balancing affair
  8. 16. With a precise molecular blade, I cleave lipids, releasing messengers from their membrane cascade
  9. 17. I am the bridge between worlds, transforming external messages into the internal language of the cell
  10. 19. Like whispers swelling to a roar, I am the cascade's decree, a single spark igniting exponential glee
  11. 20. As a versatile workhorse, I am a symphony of molecules, my roles in cellular structure, function, and signaling never cease
Down
  1. 1. Cellular Signaling Riddles (Revised)
  2. 2. I am a fleeting whisper, delivering a message at the cellular door but never stepping inside
  3. 3. Bound to GDP I patiently wait, but exchange it for GTP, and I ignite, activating effectors with all my might
  4. 4. A solitary traveler with GTP as my guide, I navigate signaling pathways, my influence vast, though I stand alone
  5. 8. I am phosphorylation's counterpoint, removing the phosphate, inactivating the signal, maintaining balance in the cellular domain
  6. 10. As a vigilant gatekeeper, I maintain the delicate balance of cellular signals, ensuring that life's story unfolds as it should
  7. 13. In my embrace, the alpha subunit sleeps, awaiting the exchange factor's signal, releasing me so the transduction story can begin
  8. 14. A piece of a larger design, I am a modular component, finding purpose and might when united with my kind
  9. 18. I am a cyclic ring of power, unleashed by a whisper, activating giants within the cellular wall
