Term
| Equation for change of energy of transport |
|
Definition
ΔGt = RT ln(C2/C1)+ZFVm
ΔGt = Joules/mol
C1/C2 = concentrations (2 = destination, 1 = source)
ZFVm measures electric difference |

Term
| simple vs. facilitated diffusion |
|
Definition
simple diffusion without (CO2 and O2 moving though cell membrane, not too polar and can diffuse quickly)
Is water moving though an aquaporon facilitated? |

Channels and Transporters
Channels can't get saturated, things just flow through
Transporters move one by one, like a revolving door. They can get saturated. |

|
Term
| secondary active transport |
|
Definition
Couples the movement of one solute with the movement of another. Uses the energy of one to power the movement of another.
Example: glucose sodium transporter |
