6. A type of protein that helps catalyze chemical reactions
8. A molecule made of many monomers (subunits).
10. An organic macromolecule used for energy. The monomer units are monosaccharides.
12. These bonds hold amino acids/ polypeptides together.
13. The reactant that enzymes work on during a chemical reaction
14. A complex sugar made of many monosaccharides. An example is starch.
15. A compound with a pH of less than 6.9
16. Something that causes a reaction to occur
18. Acid An organic macromolecule made of many nucleotides. Examples are DNA and RNA.
19. This is a monomer of nucleic acids. These contain a phosphate group, a sugar, and a base.
22. Energy The amount of energy needed to start a chemical reaction
23. Fats and oils are examples, the monomer is usually glycerol with fatty acid chains.

1. A compound with a pH greater than 7.1
2. A chemical test for proteins and polypeptides.
3. This monomer is a simple sugar whose chemical structure (shape) is a ring. An example is glucose.
4. The simplest/ most basic unit of the molecules that make up living things. These subunits can be bonded together to make up macromolecules.
5. Term that describes compounds that have either Carbon or Hydrogen, or neither.
7. A compound with a pH of 7
8. Also called polypeptides, these are made of many amino acids held together by peptide bonds.
9. A chemical test for simple sugars (monosaccharides).
11. Acid Made of many nucleotides, this molecule carries genetic instructions.
16. Bond A type of bond between two atoms, such as between carbon and hydrogen
17. Term that describes compounds that have Carbon and Hydrogen
20. A brown paper bag can be used to detect the presence of this macromolecule.
21. A chemical test used to detect the presence of starch.
22. Acid This is a monomer of proteins. Many of these are held together by peptide bonds. There are 20 very common ones.
