Across
- 2. the process by which the structure of a protein is changed by factors such as acidity and temperature
- 6. large molecules that are made by the cell
- 8. 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
- 9. net movement of water molecules across a partially permeable membrane and down a concentration gradient
- 17. having a higher concentration of dissolved substances than the solution to which it is compared
- 20. organic compound (e.g. sugars,starch,glycogen)
- 21. process of decoding the genetic instructions in mRNA into a protein (polypeptide chain) built of amino acids
