- 9. attraction between molecules of different substances
- 11. pockets in the folds on enzyme surfaces where the substrate binds and a chemical reaction occurs
- 12. (fats); Carbon, Hydrogen, and Oxygen
- 13. Carbon, Hydrogen, Oxygen, and Nitrogen
- 14. a substance on which an enzyme acts during a chemical reaction to help lower activation energy
- 15. During non-competitive inhibition, molecules do not sit in the active site but will attach to an _______.
- 16. Molecules do not sit in the active site but will attach to an allosteric site and changes the shape of the enzyme therefore changing the shape of the active site.
- 19. A water molecule is ____ if there is an uneven distribution of electrons between the hydrogen atoms and oxygen atoms. The negative pole is near the oxygen atom and the positive pole is near the hydrogen atoms
- 22. a substance formed by the chemical combination of two or more elements in definite proportions
- 23. tendency of water to rise in a thin tube
- 25. molecules forming ionic or a hydrogen bond with water molecules. “Water loving”
