Carbon

3. Process in which the cells of living things break down glucose with oxygen to produce carbon dioxide, water, and energy.
5. Hydrocarbon that contains only single bonds between carbon atoms.
6. Hydrocarbon that contains at least one double or triple bond between carbon atoms.
8. Biochemical compound such as fat or oil that contains oxygen in addition to carbon and hydrogen and is made up of long carbon chains called fatty acids.
10. Any carbon-based compound found in living things (carbohydrate, protein, lipid, or nucleic acid).
12. Biochemical catalyst that speeds up chemical reactions in living things.
13. Small molecule that forms covalent bonds with other small molecules to produce a large molecule called a polymer.
14. Biochemical compound that contains oxygen, nitrogen, and sulfur in addition to carbon and hydrogen and is made up of one or more chains of smaller molecules called amino acids.
15. Biochemical compound such as sugar, starch, or cellulose that contains oxygen in addition to carbon and hydrogen.
17. Carbon-based compound that contains only carbon and hydrogen.
18. Unsaturated hydrocarbon that contains at least one triple bond between carbon atoms.

1. Biochemical compound (either DNA or RNA) that contains oxygen, nitrogen, and phosphorus in addition to carbon and hydrogen and is made up of one or two long chains of smaller molecules called nucleotides.
2. Process in which plants and certain other organisms use light energy to synthesize glucose from carbon dioxide and water and release oxygen.
4. Unsaturated cyclic hydrocarbon that has a strong aroma and alternating single and double bonds between carbon atoms.
7. Saturated hydrocarbon that contains only single bonds between carbon atoms.
9. Large molecule that consists of many smaller molecules, called monomers, joined together by covalent bonds.
11. Compound that has the same chemical formula as another compound but has molecules with a different shape and may have somewhat different properties.
16. Unsaturated hydrocarbon that contains at least one double bond between carbon atoms.
