Across
  1. 6. electrical way to prevent polyspermy (ca2+ rise repels (+) charged sperm)
  2. 8. attracts sperm, chemotaxis, hyperactivation, increases SLE
  3. 9. activates adenylate Cyclase, phosphorylates proteins
  4. 12. chemical way to prevent polyspermy (has zinc and ovastacin)
  5. 14. removes cholesterol on sperm
  6. 15. prevents binding of spent to zona pellucida
  7. 16. receives electrical signals from NT’s
  8. 17. protein that has hyalauronidase to break down cumulus oophorus
  9. 18. egg receptor that recognizes sperm receptor
  10. 19. recognizes L-selectin receptors and anchors to endometrium
Down
  1. 1. coagulates sperm
  2. 2. happens to acrosome on zona pellucida to degrade it after ca2+ influx
  3. 3. activated by P4 ca2+ influx
  4. 4. hardens zona pellucida and sheds Juno
  5. 5. sperm receptor that recognizes egg receptor
  6. 7. helps dissolve coagulated sperm
  7. 10. the smallest unit of life
  8. 11. exocytosed during slowblock caused by ca2+ influx
  9. 13. receptor that recognizes ZP3 antigen on zona pellucida, opens catsper channels
