Across
- 6. a specific protein catalyst that acts to increase the rate of a chemical reaction within the cell by lowering the amount of energy required for the reaction to proceed
- 8. organelles containing RNA that are major sites of protein production in cells in both eukaryotes and prokaryotes
- 9. part of the coding region of a gene that is both transcribed and translated
- 11. substances such as non-polar molecules, that are insoluble in water
- 12. a stack of flattened, fluid filled membranous sacs, known as thylakoids

- 24. refers to compound that dissolves easily in water
Down
- 1. sequences of three bases in a messenger RNA
- 2. substances such as polar molecules and ionic compounds, which dissolve readily in water because they readily form hydrogen bonds with water molecules

- 4. process of copying the genetic instructions present in DNA to messenger RNA
- 5. the process by which the structure of a protein is changed by factors such as acidity and temperature
- 7. large molecules that are made by the cell
- 10. a small molecule that acts as a building block for macromolecules
- 14. compound containing adenosine and three molecules of phosphate
- 16. organic compound (e.g. sugars,starch,glycogen)
- 17. the basic building blocks of nucleic acids
- 18. process of decoding the genetic instructions in mRNA into a protein (polypeptide chain) built of amino acids
- 22. net movement of water molecules across a partially permeable membrane and down a concentration gradient
