What is selectively permeable? | Certain molecules can pass through, but not all. |
What are pores? | Small holes that allow very small molecules to move in and out freely. |
What are the two main types of transport? | Active and passive transport |
What is passive transport? | Molecules move from high to low, without ATP energy |
What is active transport? | Molecules move from low to high, with ATP energy |
What is diffusion? | The movement of molecules from areas of high concentration to areas of lower concentration due to random movement. |
What is a Concentration gradient? | The term used to describe the difference between higher and lower concentration. |
What is osmosis? | the movement of water across a membrane due to diffusion. |
What does equilibrium mean? | The point at which the molecules are evenly dispersed |
What is Hypertonic? | having a higher osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid. |
What is Hypotonic? | having a lower osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid. |
What is Isotonic? | denoting or relating to a solution having the same osmotic pressure as some other solution, especially one in a cell or a body fluid. |
What is Anaerobic Respiration? | Respiration without oxygen, produces less ATP |
What is Aerobic Respiration? | Respiration with oxygen, produces more ATP |
What is ATP energy? | able to store and transport chemical energy within cells. |
