  1. 1. found attached to the receptor in the fight or flight signalling pathway
  2. 7. the gene and protein involved in halting a cell while DNA repairs, initiates repair enzymes, and initiates apoptosis if repair is not successful
  3. 9. genes that code for proteins that progress the cell cycle
  4. 10. genes that code for proteins that stop the cell cycle
  5. 12. if these occur to any protein involved in cell cycle regulation or cell signalling, undesired results may occur
  6. 13. this is true of the new cells at the end of Mitosis compared to the parent cell
  7. 16. enzymes that activate others by phosphorylation (adding a phosphate from ATP)
  8. 17. the ligands involved in endocrine signalling
  9. 18. the enzyme involved in initiating progression through the cell cycle
  10. 20. type of receptor that involves a channel being opened or closed
  11. 22. channels that physically connect
  12. 25. the chemicals involved in short distance signalling between nerve cells
  13. 28. long distance communication between cells where signals are sent through the bloodstream
  14. 30. passing and amplifying a signal from the outside to the inside of a cell
  15. 31. the end goal of any signal transduction pathway
  16. 32. the stage of the cell cycle that involves the final cytoplasmic division into two new daughter cells
Down
  1. 2. the process that occurs during transduction where one enzyme activates another which activates another using ATP
  2. 3. the short distance communication that occurs among some bacteria to determine overall density
  3. 4. the stage of the cell cycle that involves equally dividing chromosomes and pushing them to opposite sides of the cell
  4. 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
  5. 6. a feedback mechanism that involves producing a response until a set point is reached and then decreasing the response
  6. 7. channels that physically connect adjacent plant cells and are used in direct cell to cell communication
  7. 8. a feedback mechanism that involves continuously increasing a response until the event is over
  8. 11. the checkpoint where proper DNA replication will be checked
  9. 14. the immune cells that activate Tcells in a form of direct cell to cell communication
  10. 15. the letters that represent the order of the phases of Mitosis
  11. 19. signals that must be received by cells in G0/G1 if they are to proceed through the rest of the cell cycle
  12. 21. the stage of interphase when DNA is replicated
  13. 22. the checkpoint where proper cell growth will be checked
  14. 23. programmed cell death that occurs if a cell is unfit to progress through the cell cycle
  15. 24. the second messenger sometimes required in a signalling pathway
  16. 26. the result that occurs if cells progress unregulated through the cell cycle
  17. 27. type of receptor to which epinephrine binds; has a multi-subunit protein that detaches and goes to activate other things
  18. 29. any signalling molecule that binds to the receptor
