|
Definition
|
|
Term
|
Definition

Term
| Is a protein Channel able to change shape for a molecule trying to come through that cant exactly fit?? |
|
Definition
|
|
Term
| Which type of channel is specific and only allows one type of ION to pass through?? |
|
Definition
|
|
Term
| What does the Channel do to help the cell maintain homeostasis?? |
|
Definition
| It opens and closes to allow the IONS to move which regulates the ION concentration in the cell. |
|

Term
|
Definition
| Moves materials from low to high concentration. It moves against the concentration gradient. |
