Term
|
Definition
| Double layered sheet at the core of nearly all cell membranes |
|
|
Term
|
Definition
| The movement of a substance through the cell membrane. Usually goes from an area of high concentration to an area of low concentration |
|
|
Term
|
Definition
| Movement of water molecules through a membrane from an area of higher concentration to an area of lower concentration |
|
|
Term
|
Definition
| Solute concentration is equal in both the cell and in the solution; net movement is equal |
|
|
Term
|
Definition
| Solute concentration is higher within the cell, and the ater moves into the cell to even it out |
|
|
Term
|
Definition
|
|
Term
|
Definition
| Solute concentration in solution is higher than in the cell and water leaves the cell to even it out |

|
|
Term
|
Definition
| The cells ability to choose what passes through the cell membrane and what does not |
|
|
Term
|
Definition
| When carrier proteins aid in carrying larger molecules that might usually need help through a membrane |
|
|
Term
|
Definition
| A type of transport that energy is necessary for |
|
|
Term
|
Definition
| Proces in which the cell engulfs and takes in a substance by forming a vesicle around it |
|
|
Term
|
Definition
| Type of endocytosis that takes in a liquid |
|
|
Term
|
Definition
| Type of endocytosis that involves the cell engulfing a solid |
|
|
Term
| Receptor mediated endocytosis |
|
Definition
| Type of endocytosis that requires the substance to bind to a membrane bound receptor |
|
|
Term
|
Definition
| Reverse of endocytosis; substances in vesicel fuse with cell membrane and the contents are released from the cell |
|
|
Term
|
Definition
| One binds to receptor site on protein carrier which releases the other; for every three sodium (Na+) two potassium move (K+) |
