Describe 3 type of mediated transporters and describe:
|
Uniporters: transport a single molecule at a time, Symporters: simultaneously transport 2 diff molecules in same direction
Antiporters: transport 2 diff mol in opposite direct. |
|
|
Describe facilitated diffusion (passive diffusion)
|
Facilitated diffusion: transport molec. from high [ ] --> low [ ] ==> equilibration [ ] gradient
also incl. K+ channels transport |
|
|
Describe Active transport
|
Active transport of molecules from low [ ] to high [ ], termodyn. unfav. needs to coupled with exergonic process, (hydrolysis of ATP)
