Across
  1. 3. barrier that prevents chemical reactions from occurring; this barrier needs to be met and overcome for chemical reactions to take place
  2. 5. location on enzyme where substrate binds
  3. 9. basic unit of life
  4. 11. reactants in an enzyme-catalyzed reaction
  5. 13. variable that is manipulated by the scientist to test their hypothesis
  6. 16. type of energy that is stored due to objects position or condition
  7. 17. type of reaction in which there is an overall/net release in energy; using ATP is an example
  8. 20. enzymes _______activation energy to speed up chemical reactions
  9. 24. all chemical reactions that occur in an organism
  10. 26. the structural unit that consists of substrate bound to enzyme
Down
  1. 1. type of energy that is due to objects' movement or motion
  2. 2. type of graph used to compare the averages of different worded categories
  3. 4. processes the break old bond and form new bonds; rearranged atoms to make new substances from old substances
  4. 6. form of potential energy stored in chemical bonds of molecule
  5. 7. type of graph used to determine pattern or relationship between independent and dependent variable
  6. 8. new substances formed after a chemical reaction; placed after the arrow in a chemical reaciton
  7. 10. the capacity to cause change
  8. 12. after supporting with a chemical reaction, enzymes can be ______ to support with another round of chemical reactions
  9. 14. energy currency within cells, molecule that stores energy to be directly used by cells
  10. 15. biological catalysts that are proteins; speed up chemical reactions by lowering activation energy
  11. 18. type of reaction in which there is an overall/net absorption of energy; making ATP is an example
