Across
- 5. Carbon-containing molecules found in living organisms and are essential for life processes.
- 7. The minimum amount of energy required to initiate a chemical reaction. Enzymes lower the required energy, allowing reactions to occur more quickly.
- 9. The specific region on an enzyme where the substrate binds. This site has a unique shape that fits only particular substrates.
- 11. A structural change in an enzyme at its active site; this will cause the enzyme to stop functioning. Denaturation can be caused by factors like extreme temperatures or pH levels.
- 12. Anything that speeds up a chemical reaction
- 13. The process by which living organisms maintain a stable internal environment despite changes in external conditions
- 14. Fats, oils or waxes that provide living things with stored energy, insulation, protection, and waterproofing.
- 15. The molecules that are produced during a chemical reaction.
Down
- 1. A macromolecule made of amino acids. Proteins can be structural (building parts of cells) or functional (doing specific jobs like speeding up chemical reactions).
- 2. A macromolecule made of sugar monomers (monosaccharides). Used mainly as a quick energy source for living things.
- 3. The molecules that go into a chemical reaction.
- 4. The tendency of an enzyme to catalyze a specific reaction or to act on a specific substrate. This is often compared to a "lock and key" model, where only the correct key (substrate) fits into the lock (enzyme)
- 6. A protein that acts as a biological catalyst, speeding up chemical reactions in living organisms without being consumed in the process.
- 8. A macromolecule made of nucleotides. It stores and transmits genetic information in living things.
- 10. All the chemical reactions that occur inside a living thing to maintain homeostasis, including processes that build up or break down substances.
