1. 3. protein/ (of a reaction or process) accompanied by the release of heat.
  2. 5. any of a class of organic compounds that are fatty acids or their derivatives and are insoluble in water
  3. 7. protein/ protein that accelerates the speed of chemical reactions such as digestive enzymes which break down food in the digestive tract
  4. 8. a substance produced by a living organism that acts as a catalyst to speed up a specific biochemical reaction.
  5. 10. a molecule containing a very large number of atoms, such as a protein, nucleic acid, or synthetic polymer.
  6. 12. a figure expressing the acidity or alkalinity of a solution on a logarithmic scale on which 7 is neutral, lower values are more acid, and higher values more alkaline
  7. 13. form the basic structural unit of a nucleic acid
  8. 16. energy/ the minimum quantity of energy that the reacting species must possess in order to undergo a specified reaction.
  9. 18. reaction/ transformation of one molecule to a different molecule inside a cell and mediated by enzymes
  10. 21. protein/ move many substances throughout the body. An example is hemoglobin that transports oxygen from the lungs to the other parts of the body to be used by cells in cellular respiration
  11. 22. bonding/ an attraction between atoms that allows the formation of chemical substances that contain two or more atoms
  12. 23. the chemical processes that occur within a living organism in order to maintain life.
  1. 1. a molecule that can be bonded to other identical molecules to form a polymer.
  2. 2. (of a reaction or process) accompanied by or requiring the absorption of heat.
  3. 4. the process of breaking down food by mechanical and enzymatic action into substances that can be used by the body.
  4. 6. protein/ used for support such as connective tissue and keratin that forms hair and finger nails.
  5. 9. any of a large group of organic compounds occurring in foods and living tissues and including sugars, starch, and cellulose
  6. 11. (of a reaction or process) accompanied by the release of heat.
  7. 12. any of a class of nitrogenous organic compounds that consist of large molecules composed of one or more long chains of amino acids and are an essential part of all living organisms, especially as structural components of body tissues such as muscle, hair, collagen, etc., and as enzymes and antibodies
  8. 14. a molecule that binds to an enzyme and decreases its activity
  9. 15. stance that has a molecular structure consisting chiefly or entirely of a large number of similar units bonded together
  10. 17. Acid/ a complex organic substance present in living cells, especially DNA or RNA, whose molecules consist of many nucleotides linked in a long chain.
  11. 19. protein/ help control movement such as proteins in the muscles which help control contraction.
  12. 20. acids/ a simple organic compound containing both a carboxyl (—COOH) and an amino (—NH2) group.
