Vocabulary Review – Water, Macromolecules, Enzymes
Across
- 3. Build and repair body structures, enzymes, transport, and regulation.
- 4. A molecule with slightly charged ends (positive & negative).
- 9. Energy The amount of energy needed to start a chemical reaction.
- 11. Attraction between water molecules and other substances (ex: water sticking to plant cell walls to move upward).
- 13. Monomer of carbohydrates (simple sugars like glucose, fructose).
- 14. Acids Store and transmit genetic information.
- 16. Monomer of proteins.

Down
- 1. Polymer of proteins (chains of amino acids folded into shape).
- 2. Provide immediate energy.
- 3. Polymer of carbohydrates (starch, glycogen, cellulose).
- 5. All chemical reactions that occur in living organisms to maintain life. Water is essential for metabolism.
