Across
  1. 3. provides the muscle with energy to contract. they pick up an energy charge at an exergonic reaction, move within the cell, and release the energy to drive an endergonic reaction
  2. 4. when energy is converted from one form or another , the amount of useful energy decreases
  3. 5. chemical reactions that take place in organisms required to maintain life.
  4. 8. molecules that speed up the rate of reaction without them being used up or permanently altered
  5. 9. Made up of adenine, ribose, and two phosphate groups, has one less phosphate than ATP, a high energy bond between the second and third is broken when turned into ADP
  6. 10. non protein molecules that help enzymes function properly. water-soluble vitamins are used to help the body make coenzymes
  7. 13. a reaction that requires a net input of energy, if the products contain more energy than the reactants
  8. 15. a tendency a molecule has towards loss of complexity, orderliness and useful energy
  9. 16. that is stored or conserved in a substance
  10. 17. energy can neither be created or destroyed by ordinary processes
  11. 18. light, heat, and energy
  12. 19. when a poison or drug enters the enzyme and blocks the substrate from being able to be broken apart
  13. 23. Primary energy carrier, made up of adenine, ribose, and three phosphate groups, has more energy than ADP
  14. 24. the substance an enzyme works on
  15. 25. chemical reactions linked in sequences
  16. 27. energy of movement
  17. 28. biological catalysts, composed of proteins and synthesized by living organisms. catalyze reactions. very specific to the substrate.
  18. 29. atoms or molecules that are the reactants for an enzyme-catalyzed chemical reaction
  19. 30. molecules that hold electrons that have energy in them and transport them to other places
Down
  1. 1. any form of regulation where the regulatory molecule binds to an enzyme someplace other than the active site
  2. 2. the energy “push” to start the chemical reaction
  3. 6. a reaction that involves an endergonic reaction receiving its energy from the exergonic reaction
  4. 7. describe the quantity and quality of energy
  5. 11. When the end product of a reaction interferes with the enzyme that helped produce it
  6. 12. the capacity an organism has to do work (a force acting upon an object that causes the object to move)
  7. 14. A substance altered during a chemical reaction
  8. 15. Accompanied by the release of energy
  9. 20. A substance created as a result of a chemical reaction
  10. 21. converted to kinetic energy
  11. 22. a process that can create or destroy chemical bonds that hold atoms together
  12. 26. a “pocket” for the enzyme. fit (most of the time) perfectly with the substrate as a lock and key
