Across
  1. 2. passing and amplifying a signal from the outside to the inside of a cell
  2. 4. the signalling molecule that binds to the receptor
  3. 5. the enzyme involved in initiating progression through the cell cycle
  4. 7. long distance communication between cells where signals are sent through the bloodstream
  5. 8. the ligands involved in endocrine signalling
  6. 10. genes that code for proteins that progress the cell cycle
  7. 12. the second messenger sometimes required in a signalling pathway
  8. 15. the structures involved in direct cell to cell communication in plants
  9. 19. the process that occurs during transduction where one enzyme activates another which activates another using ATP
  10. 21. enzymes that activates others by adding a phosphate
  11. 24. the end goal of any signal transduction pathway
  12. 25. the stage of the cell cycle that involves the final cytoplasmic division into two new daughter cells
  13. 26. the short distance communication that occurs among some bacteria to determine overall density
Down
  1. 1. if these occur to any protein involved in cell cycle regulation or cell signalling, undesired results may occur
  2. 3. a feedback mechanism that involves producing a response until a set point is reached and then decreasing the response
  3. 5. the protein that increases in amount during certain phases of the cell cycle until it reaches a threshold; allowing it to bind to CDK
  4. 6. the chemicals involved in short distance signalling between nerve cells
  5. 9. a feedback mechanism that involves continuously increasing a response until the event is over
  6. 11. the checkpoint where proper cell growth will be checked
  7. 13. the letters that represent the order of the phases of Mitosis
  8. 14. this is true of the new cells at the end of Mitosis compared to the parent cell
  9. 15. the gene and protein involved halting a cell while DNA repairs, initiates repair enzymes, and initiates apoptosis if repair is not successful
  10. 16. the stage cell that involves division of the cell's nucleus and chromosomes
  11. 17. found attached to the receptor in the fight or flight signalling pathway
  12. 18. the stage of interphase when DNA is replicated
  13. 20. the result that occurs if cells progress unregulated through the cell cycle
  14. 22. genes that code for proteins that stop the cell cycle
  15. 23. programmed cell death that occurs if a cell is unfit to progress through the cell cycle
  16. 27. the checkpoint where proper DNA replication will be checked
