Across
- 10. A sugar derived from ribose by replacing a hydroxyl group with hydrogen.
- 13. A nitrogen containing compound that has the chemical properties of a base- only part of a DNA/RNA molecule that changes.
- 14. Energy-rich biomolecules that are organic compounds and used by cells to store and release energy
- 16. The minimum energy required for a reaction to occur
- 18. A macromolecule that holds cell information in a coded form.
- 19. A molecule that is produced by living organisms.
- 20. The surface where an organism lives or the substance on which an enzyme can act.
Down
- 1. The breaking down complex molecules by the addition of water; it is essential for digestion
- 2. End substances after a biological process has occurred.
- 3. A region on an enzyme that binds to a protein or other substance during a reaction.
- 4. An organic substance made of the elements carbon, hydrogen, and oxygen, and it is usually found in long chains in lipids
- 5. Complex proteins that speed up chemical reactions by lowering the amount of energy needed to get the reaction started.
- 6. A macromolecule that contains carbon, hydrogen, oxygen, and nitrogen, which is used by the body for growth and repair.
- 7. A small molecular unit that is the building block of a larger molecule
- 8. A large, covalently-bonded molecule that has a repeated structural unit.
- 9. A species that speeds up chemical reactions but doesn’t react itself.
- 11. The building block of protein and plays an important role in metabolic pathways, gene expression, and cell signal transduction regulation.
- 12. The substances that participate in a chemical reaction.
- 15. A chemical element that can form organic compounds
- 17. A macromolecule made up of mainly carbon and hydrogen atoms that is primarily used for energy storage and in cell membranes.
