Across
- 3. a substance produced by a living organism that acts like a catalysts to speed of a specific biochemical reaction
- 5. an attraction between atoms that allows the formation of chemical substances that contain two more atoms
- 6. a substance that has moleculer structure consisting chiefly or entirely of a large number of similar units bonding together
- 8. from the basic structural unit of acid
- 9. coordinate body activities such as insulin which regulates the amount of sugar in the blood
- 10. any of a class of organic compounds that are fatty acids of their diravities and are insoluble in water
- 11. a molecule that binds to an enzyme and decreases activity
- 12. any of a large group of organic compounds occurring in foods and living tissues and including sugars, starch, and cellulose
- 16. helps control movement such as proteins in the muscles which help control contraction
- 19. molecule that can be bonded to other identical molecules to form a polymer
- 20. the minimum quantity of energy that the reacting species must process in undergo a specified reaction.
- 21. a simple organic compound containing both a carboxyl and amino
- 22. are organic compounds that contain the element nitrogen as well as carbon, hydrogen, and oxygen. Proteins are the most diverse group of biologically important substances and are often considered to be the central compound necessary for life
- 23. a molecule containing a very large number of atoms such as a protein neucleic acid or synthetic polymer
- 24. protein that accelerates the speed of chemical reactions such as digestive enzymes which break down the food in the digestive tract
Down
- 1. accompanied by the release of heat
- 2. transformation from one molecule to a different molecule inside a cell and meditated by enzymes
- 4. the chemical processes that occur with in a living organism to maintain life
- 7. a complex organic substance present in living scales especially Dan and rna
- 13. the process of breaking down foods by mechanical enzymatic actions into substances that can be used by the body
- 14. accompanied by or absorption of heat
- 15. used for support such as connective tissue and keratin that forms hair and nails
- 17. 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 are more alkaline
- 18. Carrier proteins are proteins involved in the movement of ions, small molecules, or macromolecules, such as another protein, across a biological membrane. Carrier proteins are integral membrane proteins; that is, they exist within and span the membrane across which they transport substances.
