|
Define homeostasis. |
All coordinated physiological processes that maintain a standard body state. |

|
Cm is Selectively permeable based on? |
Channel size & lipid solubility of molecules. |
|
|
Channel proteins. |
H2O filled channel linking IC & EC compartments. |
|
|
Carrier Proteins. |
Bind molecules. No direct link between IC and EC compartments. |
|
|
3 types of channel proteins. |
Uniport - 1 substrate only. Symport - 2+ same direction. Antiport - 2+ opposite direction. |

|
1° Active transport. |
E obtained directly from hydrolysis. Needed for signal conduction & nutrient uptake via epithelial cells. |
|
|
2° Active transport. |
Most utilize preexisting Na+ grad. Na+ binds creating a binding site, 2nd molecule binding induces conformational change and both molecules released. |
|
|
Vesicular transport. |
Phagocytosis Endocytosis Exocytosis |
