- 5. a polysaccharide that is made up of a chain of glucose molecules joined together in covalent bonds
- 7. basic building blocks of nucleic acids
- 12. a chemical your body produces when your cells break down carbohydrates for energy
- 15. any external solution that has the same solute concentration and water concentration
- 16. the movement of molecules or ions across a cell membrane
- 17. the process which a phagocyte surrounds and destroys foreign substances and remove dead cells
- 18. the movement of water molecules from a solution with high to low concentration of water molecules
- 19. compound lipids consisting of phospholic acids nitrogen base alochol and fatty acids
- 20. chemical substances required by the body to sustain basic functions and are optimally obtained by eating
Down
- 1. an oragnic compound such as sugar or starch and is used to store energy
- 3. an extensively branched glucose polymer that animals use as an energy reserve
- 4. a process by which the cell takes in the fluids along with dissolved small molecules
- 6. a water insoluble polysaccharide made up of thousands of glucose molecules
- 8. the building blocks of the fat in our bodies and in the food we eat
- 9. any self regulating process by which biological systems tend to maintain stability
- 10. the natural movement of particles from an area of higher concentration to area of lower concentration
- 11. a type of membrane transport that does not require energy to move substances
- 13. any external solution that has a high solute concentration and low water concentration
- 14. a chemical process that occurs in plants algae and some types of bacteria where exposed to sunlight
