Across
- 6. - nutrients made up of a single sugar molecule or many sugar molecules.
- 7. transport system - a series of progressively stronger electron acceptors, with energy release t each step.
- 9. - the movement of molecules from an area of higher concentration to an area of lower concentration.
- 11. respiration - respiration that takes place without oxygen.
- 12. - to disrupt amino acid bonds by physical or chemical means, changing the protein's shape which may or may not be temporary.
- 15. solution - a solution where the concentration of solutes outside a cell is lower than that found inside the cell.
- 16. - the form of carbohydrate storage in animals.
- 18. - a three-carbon chain molecule containing three hydroxyl.
- 20. - organisms that use energy, usually light, to synthesize their own food from inorganic compounds.
Down
- 1. fermentation - chemical deposition of a carbohydrate in the absence of oxygen.
- 2. motion - the random movement of molecules.
- 3. synthesis - a series of chemical reactions that allow two molecules to bond by the formation of a water molecule.
- 4. - a permanent change in a protein's shape due to amino acid bond disruption.
- 5. solution - a solution where the concentration of solutes outside of a cell is higher than that found inside the cell.
- 8. transportation - involves the use of the cell energy to move materials across a cell membrane against the concentration gradient.
- 10. acids - long chains of carbon and hydrogen joined together.
- 13. - a process by which a constant internal environment is maintained despite changes in the internal and external environment.
- 14. - the carbohydrate that forms the cell wall of plant cells
- 17. gradient - a difference in the number of molecules or ions of a substance between adjoining regions.
- 19. - a condition in which all acting influences are balanced, resulting in a stable environment.
