11 Biology End Term 1 Review
Across
- 1. type of diffusion that gases such as oxygen do
- 5. organelle that contains digestive enzymes within the cell
- 8. type of reaction that results in smaller substrates
- 10. stem cells have this potency if they can only become one type of cell
- 14. cells are often funny shapes to increase this
- 15. the process of adding more substances to the nephron filtrate from the blood
- 17. the process that stem cells undergo to give rise to more cells
- 18. enzymes will do this if they are heated to high temperatures
- 20. blood vessels that take blood back to the heart
- 22. biomolecule that can provide structural support (e.g. cellulose)
- 23. system that includes the lungs
- 25. enzyme that catabolises proteins into amino acids
- 26. type of bulk active transport out of the cell
- 27. DNA is found here in eukaryotes
Down
- 2. part of the nephron where only salt and water are selectively reabsorbed
- 3. organelle present in both eukaryotes and prokaryotes
- 4. net transport of water into/out of cells
- 6. how many cells thick the villi and capillaries are
- 7. stem cells do this in order to become specialised cells
- 9. part of the enzyme that binds the substrate
- 11. model of enzyme activity that proposes that small shape changes occur during binding
- 12. collection of substances that the blood carries away from cells to the excretory system
- 13. speed that blood travels in the capillaries
- 16. a group of similar cells that work together to perform a specific function
- 19. process where nutrients are moved into the blood from the digestive system
- 21. energy that is reduced by enzymes
- 24. energy form required for active transport
