Cricks Cell Transpor
Cricks Cell Transport Flashcards
| Question | Answer |
|---|---|
| What organelle controls what enters and exits the cell? | cell membrane |
| The amount of solute in a given amount of solvent is called the ___ of the solution | concentration |
| What is the spreading out of the atoms of a substance until they are equally spread throughout the container holding them | Diffusion |
| The state where atoms no longer spread apart because they are evenly distributed is called | Equilibrium |
| If a substance can pass through a membrane, then the membrane is _____ to the substance | Permeable |
| What is the movement of water through a membrane. The water moves to create equilibrium. | Osmosis |
| Two solutions that have the same concentrations are said to be ___ | isotonic |
| When comparing two solutions, the one with higher concentration of solute is said to be ___ | Hypertonic |
| When comparing two solutions, the one that has a lower concentration of solute is called ___ | Hypotonic |
| A cell placed in a hypertonic solution will ___ | swell and pop |
| A cell placed in a hypotonic solution will ___ | shrink |
| The difference in concentration inside versus outside a cell is calle the ___ ___ | osmotic pressure |
| Movement of LARGE molecules through a cell membrane from high to low concentration using a PROTEIN CHANNEL but NO energy is called ___ | Facilitated diffusion |
| Movement of LARGE molecules through a cell membrane from high to low concentration using a PROTEIN CHANNEL and USING energy is called ___ | Active Transport |
| The way that cells can bring large items into the cell. This happens when the cell membrane wraps around the matter and engulfs it, taking it inside the cell. | Endocytosis |
| This process involves the cell wrapping its membrane around a large molecule, and wrapping around it, engulfing the proteins and taking it in. | Phagocytosis |
| What is the same thing as phagosytosis, but it involves taking in water rather than food. | Pinocytosis |
| This is the opposite of endocytosis. This is how cells put materials OUT of the cell by pushing it against the membrane and pinching the membrane off around the waste matter. | Exocytosis |
