Cell Transport
Information about the cell membrane and transport
| Question | Answer |
|---|---|
| The primary molecule that forms a cell membrane | Phospholipid |
| Water loving | Hydrophilic |
| These three types of molecules can diffuse through the cell membrane without help | Small molecules, nonpolar molecules, and some water molecules |
| This phrase describes how molecules in the cell membrane float together unattached | Fluid Mosaic model |
| This phrase describes the cell membrane's ability to control what enters and leaves | Selectively permeable |
| The process by which a solute Will spread from an area of high concentration to Low concentration | Diffusion |
| This word describes a condition where one area in a solution has a higher concentration than another | Concentration gradient |
| Passive transport moves this way relative to the gradient | Down or with the gradient |
| Passive transport is different from active transport in this important way | It does not use energy |
| Large molecules may diffuse through the cell membrane with the help of these molecules | Channel proteins |
| When water moves across the cell membrane due to a difference in concentration | Osmosis |
| This form of active transport involves moving material into the cell | Endocytosis |
| This part of a phospholipid is hydrophilic | The head |
| This part of a phospholipid faces away from water | The tails |
| Based upon the arrangement of the phospholipids, the cell membrane has been described using this two word term | Phospholipid bilayer |
| ATP is used to open or close a special channel protein in this form of active transport | Protein pump |
| Water will flow out of a cell if it is placed in this type of solution | Hypertonic |
| Water fearing | Hydrophobic |
| An animal cell may swell and burst in this type of solution | Hypotonic |
| Controlling the material that moves in and out of the cell helps living things maintain this | Homeostasis |
| If I have a cell in an isotonic solution, what would most likely happen if I added salt to the solution | The cell would shrink |
| This form of active transport involves moving material out of the cell | Exocytosis |
| If a large molecule uses a protein to move across the cell membrane without using any energy, it is this specific form of transport | Facilitated diffusion |
| 3 forms of passive transport | Diffusion, facilitated diffusion, osmosis |
