- 5. a molecule that binds to an enzyme and decreases its activity
- 6. a substance produced by a living organism that acts as a catalyst to speed up a specific biochemical reaction.
- 7. 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. the chemical processes that occur within a living organism in order to maintain life.
- 11. a molecule containing a very large number of atoms, such as a protein, nucleic acid, or synthetic polymer.
- 12. reaction transformation of one molecule to a different molecule inside a cell and mediated by enzymes
- 18. 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
- 19. Alphabetical

- 1. acids a simple organic compound containing both a carboxyl (—COOH) and an amino (—NH2) group.
- 2. (of a reaction or process) accompanied by the release of heat.
- 3. the process of breaking down food by mechanical and enzymatic action into substances that can be used by the body.
- 4. protein coordinate body activities such as insulin which regulates the amount of sugar in the blood.
- 9. protein used for support such as connective tissue and keratin that forms hair and finger nails.
- 10. any of a large group of organic compounds occurring in foods and living tissues and including sugars, starch, and cellulose
- 13. protein help control movement such as proteins in the muscles which help control contraction.
- 14. (of a reaction or process) accompanied by or requiring the absorption of heat.
- 15. energy the minimum quantity of energy that the reacting species must possess in order to undergo a specified reaction.
- 16. acid a complex organic substance present in living cells, especially DNA or RNA, whose molecules consist of many nucleotides linked in a long chain.
- 17. bonding an attraction between atoms that allows the formation of chemical substances that contain two or more atoms
- 22. protein protein that accelerates the speed of chemical reactions such as digestive enzymes which break down food in the digestive tract
- 23. 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
