Question | Answer |
1. What is the definition of "passive transport?" | The movement of molecules across a cell membrane without energy input from the cell. |
2. What is the definition of "diffusion?" | The movement of molecules in a fluid or gas from a region of higher concentration to lower concentration. |
3. What role does diffusion play? | Small lipids and other nonpolar molecules, such as CO2 and O2, easily diffuse across the membrane. |
4. What is the definition of "concentration?" | The number of molecules of a substance in a given volume, and it can vary from one region to another. |
5. What is the definition of " concentration gradient?" | The difference in the concentration of a substance from one location to another. |
6. What is one example of this? | Tie-dye. |
7. What is a isotonic solution? | A isotonic solution has a solute concentration higher than the solute concentration inside the cell. |
8. What is a hypertonic solution? | A hypertonic solution has a solute concentration higher than the solute concentration inside the cell. |
9. What is a hypotonic solution? | A hypotonic solution has a solute concentration lower than the solute concentration inside a cell. |
10. What is the definition of "facilitated diffusion?" | The diffusion of molecules across a membrane through transport proteins. |
11. What does facilitate mean? | To make easier. |
12. What are transport proteins? | Transport proteins make it easier to enter or exit a cell. But the process is still a form of passive transport. |
13. What is osmosis? | A process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution to a more concentrated one, thus equalizing the concentrations on each side of the membrane. |
