25 Questions

1. In every living cell. Large chains of amino acids.

2. Two or more atoms held together by a covalent bond.

3. Results of the structure of atoms and their interactions with each other.

4. A compund that is able to dissolve many types of organic and inorganic compunds

5. The basic sugar unit.

6. Negative charged particles of an atom. They orbit the nucleus. They have much less mass than protons and neutrons.

7. Deoxyribonucleic acid. Two strands that pair up via a hydrogen bond. They form a double helix shape.

8. Sugare molecule in DNA

9. When a compund breaks apart and forms a new compund with a free reactant.

10. Sugar molecule in RNA

11. Contain Carbon - Hydrogen - Oxygen - Nitrogen - and sometimes sulfur and phospoirus. 20 common amino acids that make thousands of different proteins.

12. The reacting molecules of a chemical reaction.

13. Acids and bases. When combined in water they produce water and a salt (ionic compound)

14. Monomers that form nucleic acids. Each one has a sugar group and a phosphate group with a nitrogen base.

15. Form components of cel membranes.

16. Compounds that contain carbon.

17. The double helix model of DNA.

18. Center of an atom. The number of protons in the nucleus is the same as the atomic number on the periodic table of elements.

19. The force of attraction between water molecules that hold them together . A weak chemical bond.

20. Most common starch in a plant cell. It is a long chain of water insoluable polysaccharides

21. A charged atom. More protons that electrons makes a positive ion and more electrons than protons makes a negative ion.

22. A single amino acid

23. Six carbon sugars. The most commone monosaccharide. They are usually ring shaped.

24. Long term energy storage.

25. A reaction that produces energy
