Across
- 2. A nonmetallic element found more or less pure in nature (as in diamond and graphite) or as a part of coal and petroleum and of the bodies of living things or obtained artificially
- 6. A carboxylic acid with an amino group and the building block of proteins
- 8. Substance that increases the rate of a chemical reaction without being consumed itself
- 9. The substance acted on by an enzyme the enzyme breaks this down.
- 10. Process of adding a water molecule in the protein molecule to break it apart into amino acids. Now the body can use the amino acids to make its own proteins
- 14. A sugar molecule containing five carbons that has lost the -OH (hydroxyl group) on its 2' carbon
- 17. A simple compound whose molecules can join together to form polymers
- 18. Organic molecule made of smaller subunits. (proteins, carbohydrates, lipids, or nucleic acids are examples of a bio-molecules)
- 19. A chemical substance that is present at the start of a chemical reaction (will be broken down)
- 20. The energy needed to start the chemical reaction of breaking down the substrate
Down
- 1. A compound consisting of large molecules made up of simple monomers (small molecules)
- 3. Used to make muscles / made of amino acids
- 4. The active site (or active center) of an enzyme represents the small region at which the substrate(s) binds and participates in the catalysis
- 5. A nitrogen-containing molecule with basic properties
- 7. First source of energy for animals / made of mono-di-and polysaccharides
- 11. An oily organic compound insoluble in water but soluble in organic solvents, stores energy: made of fatty acid
- 12. Base unit of a lipid
- 13. Material that carries your DNA or genetic code to your offspring: made of nucleotides.
- 15. Protein that speeds up chemical reactions
- 16. A chemical substance formed as a result of a chemical reaction
