Active and Passive Transport
| Question | Answer |
|---|---|
| What happens when a cell is placed in a hypotonic solution? | The cell starts to swell and possibly explode. |
| What happens when a cell is placed in a hypertonic solution? | Can cause cell to get smaller. |
| What’s the main difference between active and passive transport? | Active transport the molecules resist the movement while during passive they just go with the flow. |
| List an example of active transport. | sodium-potassium pump |
| List the types of passive transport | diffusion, ion channels, facilitated diffusion, and osmosis |
| Why is the plasma membrane considered semipermeable? | The plasma membrane is considered semipermeable because some molecules can move through the membrane while others need to be specially transported. |
| What is the process where a cell engulfs a macromolecule, forming a vesicle? | The process where a cell engulfs a macromolecule forming a vesicle is Endocytosis. |
| What is diffusion? | Diffusion is when molecules move from an area of high concentration to an area of low concentration. |
| Explain the results of a sodium-potassium pump working across a membrane. | The results of a sodium-potassium pump working across a membrane are: it moves sodium ions to the outside of the cell and potassium ions to the inside. |
| Does facilitated transport move a substance down or up a gradient? | Facilitated transport moves a substance up. |
