Question

cell membrane transport

1. the passive movement of water across the membrane.
2. the movement of a substance from a higher concentration to a lower concentration. this is always going to be transport.
3. if two solutions have the same concentration and are isotonic.
4. the movement of a substance with a carrier protein. it does not require energy. what type of transport is this?
5. a cell placed in a solution will shrink. hypertonic
6. the movement of a substance (other than water) from a higher concentration to a lower concentration.
7. the type of transport that uses atp to move a substance from low - to high concentrations is transport.
8. defined as \cell drinking\.
9. defined as \cell eating\.
10. movement of substances to the outside of the cell using vesicles.
11. a cell placed in a solution will swell. hypotonic
12. the ability of a solution to change the shape or tone of the cell.
13. what are the primary structures of the cell membrane?
14. which biomolecule is used as a path of transport across the cell membrane?
15. the cell membrane is permeable.

Explanation:

1. Osmosis is the passive movement of water across membranes.
2. Diffusion is the movement of a substance from a higher to a lower concentration.
3. Isotonic solutions have equal solute concentrations.
4. Facilitated diffusion uses a carrier - protein and no energy.
5. A cell in a hypertonic solution shrinks.
6. Active transport moves substances from low to high concentrations using ATP.
7. Pinocytosis is “cell drinking”.
8. Phagocytosis is “cell eating”.
9. Exocytosis is the movement of substances out of the cell using vesicles.
10. A cell in a hypotonic solution swells.
11. Tonicity is the ability of a solution to change cell shape/tone.
12. The primary structures of the cell membrane are phospholipids.
13. Proteins are used as transport paths across the cell membrane.
14. The cell membrane is semi - permeable.
